The imine complexes 1 catalyzed dehydrogenative silylation of terminal alkynes, hydrosilylation of imines and alkenes, and intermolecular hydrophosphination of alkynes. Moreover, dehydrogenative double silylation of conjugated dienes was achieved with 1.

  Catalytic intermolecular hydrophosphination of alkynes with Ph,PH has been achieved by using a ytterbium-imine complex, [Yb(eta (2)-Ph(2)CNPh)(hmpa)(6)]. Thus, both terminal and internal alkynes were converted in high yields to the corresponding alkenylphosphines or phosphine oxides after oxidative workup. The present method was also applicable to various carbon-carbon multiple bonds such as conjugated diynes and dienes, allenes and styrene derivatives. (C) 2001 Elsevier Science Ltd.
