Reaction Steps
Finally, 1,1'-binaphthalene-2,2'-dioxychlorophosphine (XIV), obtained, e.g., by heating an optically active binaphthol (VII) together with phosphorus trichloride, is reacted with the 2'-diphenylphosphino-2-hydroxy-6-vinyl-1,1'-binaphthyl (XIII) obtained above, whereby 2'-diphenylphosphino-6-vinyl-1,1'-binaphthalen-2-yloxy(1,1'-binaphthalene-2,2'-diyloxy)phosphine (XV) is obtained as the target compound.
