Selective Addition of P(O)–H Bonds to Alkynes Catalyzed by Transition Metals Immobilized on Polystyrene-bound Triphenylphosphine

Addition of P(O)–H bonds to alkynes catalyzed by transition metals (Rh, Pd, and Ni) immobilized on polystyrene-bound triphenylphosphine proceeded efficiently to afford high yields of the addition products with high regioselectivity. The immobilized catalysts were easily recovered from the reaction m...

Description
Summary:Addition of P(O)–H bonds to alkynes catalyzed by transition metals (Rh, Pd, and Ni) immobilized on polystyrene-bound triphenylphosphine proceeded efficiently to afford high yields of the addition products with high regioselectivity. The immobilized catalysts were easily recovered from the reaction mixture via simple centrifugal separation and could be reused several times without severe deactivation.
