1. General Information. All reagents were used as purchased and used without further purification (E)- anethole was purchased from Aldrich and used without further purification. Unless otherwise stated, reactions were carried out under argon atmosphere. Anhydrous solvents (DMF, DMSO, THF) were dried by passing through an activated alumina column on a
PureSolvTM solvent purification system (Innovative Technologies, Inc., MA). CH3CN (Panreac, HPLC grade) and EtOH (Scharlau, anaylitical solvent) were used without any further purification. Blue LED strips (Leroy Merlin Ref. 15379721), white LED strips (Leroy Merlin Ref. 16640246) and compact fluorescent lamp (CFL) (Leroy Merlin Ref. 14640402) were used as visible light sources. Analytical thin layer chromatography was carried out using TLC-aluminum sheets with 0.2 mm of silica gel (Merck GF234). Visualization was achieved using ultraviolet light (254 nm) and chemical staining with vanillin or basic potassium permanganate solutions as appropriate. Flash column chromatography was performed on silica gel (Aldrich, 230-400 mesh). Organic solutions were concentrated under reduced pressure on a Buchi rotatory evaporator. NMR spectra were recorded at 298 K (unless otherwise stated) on a Bruker Avance 300, Bruker Avance 400 Ultrashield and Bruker Avance 500 Ultrashield apparatuses. Chemical shifts (δ) are quoted in ppm relative to residual solvent and coupling constants (J) are quoted in hertz (Hz). Multiplicity is reported with the following abbreviations: s = singlet, d = doublet, t = triplet, q = quartet, dt = doublet of triplets, td = triplet of doublets, ddd=doublet of doublet of doublets. Melting points were measured using open glass capillaries in a Buchi B540 apparatus. Infrared spectra were recorded on a Bruker Tensor 27. Mass spectra were recorded on a Waters LCT Premier spectrometer. Ad = 1-adamantanyl 2. Synthesis of styrenes 1. General Procedure A: Potassium tert-butoxide (1.0 M solution in THF, 16.1 mL, 16.1 mmol) was added to a suspension of the corresponding phosphonium salt (6.46 mmol) in THF (6.5 mL) at 0 °C. After this, the resulting reaction mixture was stirred for 30 min at room temperature. Then, the corresponding aldehyde or ketone (6.46 mmol) was added and stirred until complete conversion (the reaction was monitored by TLC). The mixture was quenched with saturated NH4Cl aqueous solution (10 mL) and extracted with AcOEt (3 x 10 mL). The combined organic extracts were washed with brine and dried over anhydrous Na2SO4 and concentrated in vacuo. The crude residues were purified by flash column chromatography on silica gel (AcOEt/hexane mixtures) affording the corresponding alkenes 1. General Procedure B: To a solution of the corresponding triphenylphosphonium bromide salt (1.2 eq, 7.7 mmol) in dry THF (0.3 M) at -78 °C, n-Butyllithium (1.6 M in hexanes, 1.2 eq, 5.25 ml) was added dropwise. The temperature of the reaction mixture was allowed to rise to 0 °C for 30 min and then the corresponding aldehyde or ketone (1.0 eq, 7.0 mmol) dissolved in THF (7 ml) was added dropwise over 20 min. The reaction mixture was stirred for 20 min at 0 ºC and then allowed to warm up to room temperature and stirred until complete conversion (the reaction was monitored by TLC). The mixture was quenched with saturated aqueous NH4Cl (10 mL) and extracted with AcOEt (3 x 10 mL). The combined organic extracts were washed with brine and dried over anhydrous

extracted with Et2O (3 x 50 ml). Combined organic layers where dried over MgSO4 and concentrated. The residue was purified by flash chromatography on silica gel (hexane 100% to hexane/EtOAc 50:1). Once the product was eluted from the column, the corresponding fractions were concentrated. If the test tubes were left in the bench the gem-diiodo reagent will slowly decompose and a pick color will appear (I2 formation). In this case, a spatula of Na2S2O3 could be added to the collected tubes and stirred until the pink color disappeared, the solid was then removed by filtration and the desired product was obtained after concentration. Note: If the gem-diiodo reagent was a liquid, it was kept in solution in MeCN (1.0–0.5M) at -30ºC under argon atmosphere. 1,2-Dichloroethane was used as external standard to calculate the concentration. If the gem-diiodo reagent was a solid, it was kept as a solid at -30ºC. Adamantan-1-yl 2,2-diiodoacetate 2a

5. Visible-light-driven cyclopropanation of styrenes: reaction scope. General procedure F (ratio 1:2 styrene:gem-diidodo) To a 10 mL reaction tube equipped with a stirring bar was added the gem-diiodo reagent 2 (0.20 mmol, 1 equiv) and the tube was sealed with a septum, degassed and filled with argon. MeCN (2ml), the corresponding styrene (0.2 mmol, 1 equiv), i-Pr2EtN (0.40 mmol, 2 equiv) and aqueous NaCl (1.25 M, 1 mL) were added. The reaction mixture was degassed by two freeze-pump-thaw cycles under argon. After that, the reaction tube was irradiated under with visible light (21W CFL at a distance of 7 cm) and a mini-fan was kept on top to maintain room temperature. After 4 h gem-diiodo reagent (0.20 mmol, 1 equiv) and i-Pr2EtN (0.40 mmol, 2 equiv) were added and the reaction mixture was stirred for 14 more hours. Then, the reaction mixture was passed through a short pad of silica gel and eluted with dichloromethane. The solvent was removed under vacuum and the residue was purified by column chromatography on neutral silica gel to give the corresponding cyclopropanes. Ratio of isomers was determined from the crude reaction mixture using 1H NMR spectroscopy. General procedure G (ratio 2:1 styrene:gem-diidodo) To a 10 mL reaction tube equipped with a stirring bar was added the gem-diiodo reagent 2 (0.20 mmol, 1 equiv) and the tube was sealed with a septum, degassed and filled with argon. MeCN (2ml), the corresponding styrene (0.4 mmol, 2 equiv), i-Pr2EtN (0.40 mmol, 2 equiv) and aqueous NaCl (1.25 M, 1 mL) were added. The reaction mixture was degassed by two freeze-pump-thaw cycles under argon. After that, the reaction tube was irradiated under with visible light (21W CFL at a distance of 7 cm) and a mini-fan was kept on top to maintain room temperature. After 18 h, the reaction mixture was passed through a short pad of silica gel and eluted with dichloromethane. The solvent was removed under vacuum and the residue was purified by column chromatography on neutral silica gel to give the corresponding cyclopropanes. Ratio of isomers was determined from the crude reaction mixture using 1H NMR spectroscopy. Note: The cis/trans configuration of cyclopropanes was determined based on the value of the J coupling constants for the benzylic and α-protons to the carbonyl group. The 3Jcis (7-13 Hz) is always larger than 3Jtrans (2-7 Hz), and this can be reliably used for the

Procedure for a 1g-scale reaction with trans-anethole: To a 250 ml round-bottom-flask was added adamantan-1-yl 2,2-diiodoacetate 2a (3.0 g, 6.76 mmol, 1 equiv) and the flask was degassed and filled with argon (x 3). Then, CH3CN (80 mL, previously degassed by bubbling argon for 15 min), E-anethole 1a (1.0 g, 6.75 mmol, 1 equiv), aqueous NaCl (1.25 M, 30 mL, previously degassed by bubbling argon for 15 min) and i-Pr2EtN (1.2 mL, 2 equiv) were added. A balloon filled with argon was placed and the reaction mixture was irradiated with 2 x 21 W CFL as visible-light source at a distance of 5 cm and stirred at room temperature. After 4 h i-Pr2EtN (0.6 mL, 1 equiv) was added and the reaction mixture was stirred for 13 h. The reaction mixture was quenched with water (150 ml) and extracted with AcOEt (3 x 100 ml). Combined organic layers were washed with brine, dried over anhydrous MgSO4 and concentrated in vacuo. Purification by flash chromatography (gradient: hexane/EtOAc 100:0 to 50:1) provided the corresponding cyclopropanes 3a (1.75 g, 75 %) as colorless oils and the remaining E-anethole (0.14 g, 15%).

Determination of Photon Flux using Ferrioxalate Actinometry The photon flux of the spectrophotometer was determined by standard ferrioxalate actinometry. 19 Two solutions were prepared: Solution A: a 0.15M solution of potassium ferrioxalate trihydrate was prepared in 0.05M H2SO4 solution. Solution B: A buffered solution of phenanthroline was prepared by dissolving phenanthroline (0.025 g, 0.14 mmol) and NaOAc (5.63 g, 68.6 mmol) in 25 mL of 0.5 M aq H2SO4.

To determine the photon flux of the spectrophotometer, 2.0 mL of the ferrioxalate solution A was placed in a cuvette and irradiated for 30 seconds at λ = 410 nm with an emission slit width at 5.0 nm. After irradiation, 0.35 mL of the phenanthroline solution was added to the cuvette. The solution was then allowed to rest for 1 h to allow the ferrous ions to completely coordinate to the phenanthroline. The absorbance of the solution was measured at 510 nm. The same procedure was repeated for 20 seconds and 10 seconds. A non-irradiated sample was also prepared and the absorbance at 510 nm measured. For the calculation of photon flux the following equations were used:
mol Fe2+= (V⦁'A)/( l⦁ε) equation 1
Photon flux = (mol Fe2+)/(I⦁t⦁f) equation 2
Where V is the total volume of the solution, 'A is the difference in absorption between the irradiated and non-irradiated solutions, l is the path length, and H is the molar absorptivity at 510 nm (11,110 L mol-1cm-1), ) is the quantum yield for the ferrioxalate actinometer, t is the time (s), and f > 0.999.

Determination of the Quantum Yield of the photocyclopropanation Under argon atmosphere, a cuvette was charged with anethole (0.1mmol, 1 equiv), DIPEA (0.2mmol, 2 equiv), reagent 2a (0.1mmol, 1 equiv) and 2ml of MeCN (previously degassed) and 0,5ml of water (previously degassed). The sample was stirred and irradiated (λ = 410 nm, slit width= 5.0 nm) for 5400 s (90 min). After irradiation, the solution was passed through a silica plug. The yield of product formed was determined by 1H NMR. The quantum yield was determined using eq 3.
I= (mol product)/(photon flux⦁t⦁f) equation 3 Where f is the fraction of light absorbed at 410nm of the reaction mixture (equation 4).
