This book highlights major achievements made in the last five years concerning sustainable C(sp³)-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(sp³)-H bond functionalization. Chapter 1 reviews transition-metal-catalyzed C(sp³)-H bond functionalization using different directing groups, while Chapter 2 addresses the new methods of transition-metal-catalyzed and metal-free C(sp³)-H bond functionalization without directing groups, in...
