,1‘-binaphthyl (2), useful as intermediates in the preparation of bidentate Lewis acids, have been synthesized from simple phenols through a two-step sequence. Thus, 2-chlorophenol, 1,2-dihydroxybenzene, and binaphthol were converted into the corresponding aryl diethyl phosphate esters 4−6, which on reaction with sodium trimethylstannide (3) in liquid ammonia, under irradiation, afforded 1 and 2, respectively
