To obtain the subject new compound of a specific silylated ferrocenyldiphosphine, and useful for enantioselective hydrogenation catalyst, a catalyst bound to an inorganic or organic support by a silyl group and readily separated from a reaction product, or the like.
This compound is a new silylated ferrocenyldiphosphine of formula I [R1 is a 1-8C al-kyl, a (substituted) phenyl or the like; R2, R3, R10 and R11 are each a 1-12C alkyl, a 5-12C (substituted) cycloalkyl, a (substituted) phenyl or the like; R12 is a 1-12C alkyl, a 3-7C cycloalkyl, phenyl or the like; R13 is a 1-12C alkylene or phenylene; Z is Cl, NH2, an NH-(1-12C alkyl) or the like]. The compound provides a compound useful as an enantioselective catalyst capable of readily separated from the product by reacting with a silyl group to bind to an inorganic or a polymeric support. The compound is obtained by reacting a ferrocene of formula II with butyllithium, further reacting the product with a compound of the formula ClPR10R11 and a compound of the formula ClSi(R12)2-(R13)-Cl, and further reacting the product with a compound of the formula HPR2R3.
