One-pot synthesis of binaphthyl-based phosphines via direct modification of BINAP

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.

Synthesis, crystal structure, dynamic behavior and reactivity of dinaphtho[2,1-b:1',2'-d]phospholes and related atropisomeric phosphacyclic derivatives

7-Phenyldinaphtho[2,1-b:1',2'-d]phosphole (1b) has been prepared by reaction of dichlorophenylphosphine either with 2,2'-dilithio-1,1'-binaphthalene or with bis-dialin 7. In the latter case the relevant tetrahydro derivative 8 is formed at the same time.

Dinaphthophospholes: a New Class of Atropisomeric Phosphorus Ligands

The parent and some alkyl and aryl substituted dinaphthophospholes 1 have been synthesized and shown to be atropisomerically stable below room temperature.
