Abstract: Two vinyl-functionalized chiral 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP) ligands, (S)-4,4'-divinyl-BINAP and (S)-5,5'-divinyl-BINAP, were successfully synthesized. Chiral BINAP-based porous organic polymers (POPs), denoted as 4-BINAP@POPs and 5-BINAP@POPs, were efficiently prepared via the copolymerization of vinyl-functionalized BINAP with divinyl benzene… read more here.

Abstract: A series of trifunctional BINAP-based monophosphonium phase-transfer catalysts were developed and used in the asymmetric addition of α-diazomethylphosphonates to vinylogous imines formed in situ from sulfonylindoles. This methodology tolerates a broad scope of 2-unsubstituted sulfonyl… read more here.
