Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for readily producing menthyl phenylphosphinate by which an optically active enantiomer of the menthyl phenylphosphinate that can not be isolated conventionally can easily be separated, and the menthyl phenylphosphinate having high enantiomer selectivity (RP/SPor SP/RP) can be produced by using a menthoxy metal species as a starting raw material. SOLUTION: The menthyl phenylphosphinate represented by general formula (I): HP(O)(OR)Ph (wherein, R is a menthyl group) is produced by reacting the menthoxy alkali metal species represented by general formula (II): ROM (wherein, R is a menthyl group; and M is an alkali metal) with dichlorophenylphosphine, and hydrolyzing the product.
