This book highlights major achievements made in the last five years concerning sustainable C(sp)-H bond functionalization and offers a promising and emerging tool-kit for organic synthesis. The book is divided into three chapters demonstrating key advances in C(sp)-H bond functionalization. Chapter 1 reviews transition-metal-catalyzed C(sp)-H bond functionalization using different directing groups, while Chapter 2 addresses the new methods of transition-metal-catalyzed and metal-free C(sp)-H bond functionalization without directing groups, in addition to briefly highlighting redox-neutral C(sp)-H bond functionalization. In closing, Chapter 3 examines visible-light photoredox catalysis, an emerging and highly sustainable C(sp)-H bond functionalization strategy. The book offers an intriguing and useful reference guide for a broad readership working and/or interested in the fields of organic, organometallic, and green chemistry. weiterlesen
