Uozumi, Yasuhiro published the artcilePreparation of optically active binaphthylmonophosphines (MOP’s) containing various functional groups, COA of Formula: C22H12F6O6S2, the publication is Tetrahedron (1994), 50(15), 4293-302, database is CAplus.
Optically active 2′-diphenylphosphino-1,1′-binaphthyls (I, MOP’s) having various functional groups, cyano, aminomethyl, methoxycarbonyl, carboxy, and hydroxymethyl, at the C2-position were prepared A cyano group was introduced on the MOP skeleton by nickel-catalyzed cyanation of 2-diphenylphosphinyl-2′-trifluoromethanesulfonyloxy-1,1′-binaphthyl which is readily prepared from optically active binaphthol. Preparation of the MOP derivatives bearing carboxylic groups were achieved by palladium-catalyzed monocarbonylation of binaphthyl 2,2′-bis(triflate) followed by phosphinylation of the remaining triflate group.
