Cai, Dongwei published the artcileSynthesis of Chiral 2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) via a Novel Nickel-Catalyzed Phosphine Insertion, Application of (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), the publication is Journal of Organic Chemistry (1994), 59(23), 7180-1, database is CAplus.
A two-step synthesis of 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) from 1,1′-bi-2-naphthol is described. The key step is a cross-coupling reaction of the chiral ditriflate of 1,1′-bi-2-naphthol with diphenylphosphine using Ni catalysis that produces chiral BINAP in 75% yield with no racemization.
