A novel, optically active alkenylphosphinic acid ester having chirality on a phosphorus atom; and a simple process for producing the ester. An optically active, hydrogen phosphinic acid ester is reacted with an acetylene compound in the presence of a catalyst containing a metal of group 9 or 10 of the periodic table to thereby obtain a novel, optically active alkenylphosphinic acid ester which has chirality on a phosphorus atom and is represented by the following general formula [1] and/or [2].

Synthesis of Disubstituted Phosphinates via Palladium-Catalyzed Hydrophosphinylation of H-Phosphinic Acids
The first metal-catalyzed hydrophosphinylation of unsaturated hydrocarbons with H-phosphinic acids is described. A strategy to activate the PH bond through control of the tautomeric equilibrium using ethylene glycol is described. The reactions also avoid chromatographic purification.

The epoxidation of alkenylphosphorus compounds with hydrogenperoxide was systematically studied, revealing that while alkenylphosphine oxides failed to produce the corresponding epoxides, alkenylphosphonates, or phosphinates having a phenyl group at α-position reacted with H2O2/K2CO3 or alkenylphosphonic acids or phosphinic acids having an aliphatic group at α- or β-positions reacted with H2O2/Na2WO4/Et3N
