Hydrophosphination of alkynes in the presence of a palladium or nickel catalyst affords vinylphosphinates 94 or 95 in good yields (Scheme 70).[237–239] Interestingly, when monosubstituted alkynes are used, the regioselectivity of the reaction can be easily controlled by the presence of small amounts of diphenylphosphinic acid. The synthesis of enantiomerically pure O-menthyl alkenyl(phenyl)phosphinates 96 by palladium-catalyzed hydrophosphinylation of alkynes occurs stereospecifically with retention of configuration at the phosphorus atom.[239]
