For years chemists have been fascinated by reactions that transform C-H bonds, which despite their ubiquity are relatively inert. Over the past decade, the eld of transition-metal-catalyzed C-H bond functionalizations has blossomed, the fruits of which are the synthetic methods whose appeal is broad and will con- tinue to increase.

Editors Yu and Shi have assembled a timely volume consisting of 12 chapters contributed by leading scientists in the eld. The topics covered are representative of the recent literature. For example, there is a broad coverage of transformations of sp 2 - hybridized CH bonds in aromatic and heteroaromatic com- pounds. The majority of these are palladium-catalyzed reactions that generate CC bonds from CH bonds. These chapters cover CC bond formation from metal-carbon bonds in CH activation intermediates via cross-couplings with carbon elec- trophiles, e.g., organohalides, insertions of substrates containing CdC, CtC, CdN, and CdO bonds, or coupling with other CH bonds. Chapters are also dedicated to transformations of sp 3 -hybri- dized C-H bonds, which are typically more challenging. Topics include allylic C-H oxidations that form C-O bonds, insertions of C-H bonds into metal-carbene bonds, oxidations of C-H to C-N bonds, cross dehydrogenative couplings of C-H bonds, and relay-directed activations of remote C-H bonds. Given the potential applications of C-H activations in indus- trial settings, two chapters are devoted to transformations of pyrroles, indoles, and more densely heteroatom substrates like diazines and azole N-oxides. Likewise, chemistry mediated by less expensive metals like iron, copper, and ruthenium is dis- cussed, complementing methods utilizing more precious cata- lysts like palladium and rhodium. The consistent theme uniting the chapters is the application to organic synthesis. Examples range from construction of pharma- ceutically relevant compounds to functionalization of C-H bonds of complex molecules in the arena of total synthesis. Without question, methodology is the main focus in this volume. Never- theless, a reasonable balance is struck with discussions of mech- anistic underpinnings of catalytic transformations gleaned from both experiment and theory. There is little discussion of chem- istry relevant to the synthesis of commodity chemicals, but doing so would have compromised the focus of the work. The coverage with regard to the literature is excellent. The development of the eld is highlighted by seminal contributions from its pioneers, and each chapter includes numerous examples of developments through 2009. Consequently, this volume should appeal to a wide audience of chemists, including students who are learning about C-H activation to scientists in academia and industry who wish to apply C-H bond functionalizations to their research.

Review of C-H Activation. Topics in Current Chemistry, 292

Review of C-H Activation. Topics in Current Chemis-try, 292. Edited by Jin-Quan Yu. (Scripps Research In-stitute, La Jolla, CA) and Zhangjie Shi. (Peking University,Beijing, China). Springer-Verlag: Berlin, Heidelberg. 2010.xx þ 384 pp. $309. ISBN 978-3-642-12355-9.

For years chemists have been fascinated by reactions thattransformC-Hbonds, which despite their ubiquity are relativelyinert. Over the past decade, the field of transition-metal-catalyzedC-H bond functionalizations has blossomed, the fruits of whichare the synthetic methods whose appeal is broad and will con-tinue to increase. Thus, it is fitting that Volume 292 in the Topicsin Current Chemistry series is dedicated to C-H activation.

Editors Yu and Shi have assembled a timely volume consistingof 12 chapters contributed by leading scientists in the field. Thetopics covered are representative of the recent literature. Forexample, there is a broad coverage of transformations of sp2-hybridized C—H bonds in aromatic and heteroaromatic com-pounds. The majority of these are palladium-catalyzed reactionsthat generate C—C bonds from C—H bonds. These chapterscover C—C bond formation from metal-carbon bonds in C—Hactivation intermediates via cross-couplings with carbon elec-trophiles, e.g., organohalides, insertions of substrates containingCdC, CtC, CdN, and CdO bonds, or coupling with otherC—H bonds.

Chapters are also dedicated to transformations of sp3-hybri-dized C-H bonds, which are typically more challenging. Topicsinclude allylic C-Hoxidations that formC-Obonds, insertionsof C-H bonds into metal-carbene bonds, oxidations of C-HtoC-Nbonds, cross dehydrogenative couplings of C-Hbonds,and relay-directed activations of remote C-H bonds.

Given the potential applications of C-H activations in indus-trial settings, two chapters are devoted to transformations ofpyrroles, indoles, and more densely heteroatom substrates likediazines and azole N-oxides. Likewise, chemistry mediated byless expensive metals like iron, copper, and ruthenium is dis-cussed, complementing methods utilizing more precious cata-lysts like palladium and rhodium.

The consistent theme uniting the chapters is the application toorganic synthesis. Examples range from construction of pharma-ceutically relevant compounds to functionalization of C-Hbonds of complex molecules in the arena of total synthesis. Withoutquestion, methodology is the main focus in this volume. Never-theless, a reasonable balance is struck with discussions of mech-anistic underpinnings of catalytic transformations gleaned fromboth experiment and theory. There is little discussion of chem-istry relevant to the synthesis of commodity chemicals, but doingso would have compromised the focus of the work.

The coverage with regard to the literature is excellent. Thedevelopment of the field is highlighted by seminal contributionsfrom its pioneers, and each chapter includes numerous examplesof developments through 2009. Consequently, this volume shouldappeal to a wide audience of chemists, including students who arelearning about C-H activation to scientists in academia and

industry who wish to apply C-H bond functionalizations to theirresearch.

Lastly, this volume is dedicated to the memory of Keith Fagnou,who was also a contributing author. Mark Lautens and MarkTaylor provide a poignant obituary that captures the essence of arising star who left us too soon. This treatise on C-H activationis a fitting tribute to Keith’s memory.
