Abstract

A di-substituted metallocene compound having good quality can be synthesized completely at a low cost in a high yield in a easy manner by reacting a metallocene dihalide with a Grignard reagent which is a compound represented by formula (I): RMgX (wherein R represents an aryl, benzyl or diaryl phosphinomethylene group which may have a substituent and X represents a halogen element) under specified conditions.
