Title:
光学活性な１，２−ビス（ジアルキルホスフィノ）ベンゼン誘導体の製造方法
Document Type and Number:
Japanese Patent JP5599664
Kind Code:
B2
Abstract:
An industrially advantageous method for producing an optically active 1,2-bis(dialkylphosphino)benzene derivative of the present invention is provided. The method is characterized in that a phosphine-borane compound represented by the following general formula (1) is subjected to a deboronation reaction, followed by lithiation, then the reaction product is subjected to reaction with an alkyldihalogenophosphine represented by RaPX′2, and thereafter the reaction product is subjected to reaction with a Grignard reagent represented by RbMgX″ to produce an optically active 1,2-bis(dialkylphosphino)benzene derivative (A). R1 and R2 respectively represent an alkyl group having 1 to 8 carbon atoms, and the number of carbon atoms is different between R1 and R2. Ra is either R1 or R2 and Rb is the other of R1 and R2. X, X′, and X″ each represent a halogen atom.
