Abstract
This chapter describes recent developments in the manganese-catalyzed crosscoupling reactions for the formation of CC or C-heteroatom bonds, including C-N, CO , C-S and C-B bonds. The nature of the organic halide and the organometallic coupling partner (organolithium, Grignard or organostannyl reagents) are important parameters in these reactions. Mechanistic studies are discussed as well as the recently arisen question about the influence of trace-metal contamination in certain reactions.
