| abstract | (57) [Summary] [Objective] 2,2'-bis (diphenylphosphinylmethyl) -1,1'- which can be simply and reliably carried out and can obtain a desired product in high yield and purity. Develop a manufacturing method for binaphthyl. [Structure] 2,2'-bis (bromomethyl) -1,1'-binaphthyl prepared by reacting 2,2'-dimethyl-1,1'-binaphthyl with a brominating agent in a solvent The reaction mixture, which further comprises brominated binaphthyl, is treated, optionally after removal of unreacted brominating agent, reacted brominating agent and / or solvent, with the formula RO-P (Rh- An alkyldiphenylphosphinite represented by (R ′) n ) 2 is reacted at 70 to 180 ° C. in the presence or absence of another solvent to give 2,2′-bis (diphenylphosphini). Rumethyl) -1,1'-binaphthyl is prepared. |
