A Multipurpose Gold(I) Precatalyst. — Bis(2,4,6-trimethoxybenzonitrile)gold(I) hexafluoroantimonate is shown to be an air stable, highly versatile precatalyst of active and robust gold complexes which catalyze the cyclopropanation of enyne (I), themethoxy cyclization of enyne (IV), and the skeletal rearrangement of enyne derivatives (IV) and (VIII). — (RADUCAN, M.; RODRIGUEZ-ESCRICH, C.; CAMBEIRO, X. C.; ESCUDERO-ADAN, E. C.; PERICAS*, M. A.; ECHAVARREN, A. M.; Chem. Commun. (Cambridge) 47 (2011) 17, 4893-4895, http://dx.doi.org/10.1039/c1cc10293a ; Inst. Chem. Res.
