Cobalt- and Nickel-Catalyzed Functionalization of Unactivated C–Hal, C–O and C–H Bonds

First row transition-metal-catalyzed C–C/C–N bond formations through the functionalization of unactivated C–Hal, C–O and C–H bonds have been developed. The inexpensive nickel and cobalt complexes were introduced to facilitate different kinds of novel reactions and even the indole synthesis
