METHOD FOR PRODUCING DIPHOSPHINE COMPOUND, DIPHOSPHINE COMPOUND PRODUCED BY SUCH PRODUCTION METHOD, AND INTERMEDIATE PRODUCT

摘要

Disclosed is a novel method for producing a diphosphine compound which enables to obtain diphosphine compounds of various structures by a simple synthesis process. Also disclosed are a diphosphine compound produced by such a production method and an intermediate product therefor. Specifically disclosed is a method for producing a diphosphine compound wherein an intermediate product is synthesized by a coupling reaction between a bis(phosphine)boronium salt and an electrophile having at least two electrophilic moieties, and then the intermediate product is treated with a boronium-removing agent.
