Optically active alkenylphosphinic acid esters and process for producing the same

摘要

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]. R<1>{CH=CR<2>[P(O)(OR<3>)Ar]}n [1] R<1>{C[P(O)(OR<3>)Ar]=CHR<2>}n [2]
