Catalytic addition of C - H bonds to C - C multiple bonds

During the last decade, catalytic functionalization of C-H bonds has become one of the most attractive research areas in modern organic synthesis. To date, many efficient catalytic reactions have been reported. In almost all of these reactions, heteroatom-directed C-H bond cleavage and/or C-C bond formation are quite important for attaining high regioselectivity and efficiency. In this chapter, several representative results concerning transition metal-catalyzed alkylation of C-H bonds with olefins, alkenylation with acetylenes, and carbonylation with olefins and carbon monoxides will be briefly reviewed.
