Herein reported is the convenient and efficient strategy for the preparation of binaphthyl-based phosphines through direct modification to the commercially available 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) with sodium. In the absence of 15-crown-5-ether, a cyclic sodium dinapthylphospholide intermediate is mainly generated. With 15-crown-5-ether, P-Ph bonds are selectively cleft by Na to produce binaphthyl-based disodium phosphides. The mechanism of selective formation of sodium dinapthylphospholide or binaphthyl-based disodium phosphides is proposed.
