Regio- and stereoselective synthesis of alkenylphosphines: a rhodium-catalyzed hydrophosphination of alkynes using a silylphosphine.
A novel rhodium-catalyzed hydrophosphination of alkynes using a silylphosphine as a phosphino group source is described. A variety of alkynes, both terminal and internal ones with aryl, alkyl, and carboxyl groups, gave the corresponding alkenylphosphines in a highly regioselective and syn-selective manner. Alkenes with an electron-withdrawing group also gave the corresponding adducts in good yields.
