Efficient and Selective Nickel-Catalyzed Addition of H-P(O) and H-S Bonds to Alkynes

摘要

Metal complex-catalyzed additions of a heteroatom compound H-Z (Z = a heteroatom or group) to a carbon-carbon unsaturated bond (Scheme 1) is one of the most straightforward ways for the preparation of heteroatom compounds, which have wide applications in organic synthesis and industrial processes.1 Whereas the second and third row VIIIB metals have been frequently used as the catalysts for these reactions, the corresponding first row metals were often known to show lower catalytic activity and/or give unsatisfactory results.
