Abstract
Catalytic intermolecular hydrophosphination of alkynes with Ph2PH has been achieved by using a ytterbium-imine complex, [Yb(η2-Ph2CNPh)(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.
