Armanino, Nicolas published the artcileElectrophilic Trifluoromethylation of Primary Phosphines: Synthesis of a P-Bis(trifluoromethyl) Derivative of BINAP, Quality Control of 126613-06-7, the publication is Organometallics (2010), 29(7), 1771-1777, database is CAplus.
The new chiral diphosphine ligand (R)-(2′-(bis(trifluoromethyl)phosphino)-1,1′-binaphthyl-2-yl)diphenylphosphine (2, Ph2PC10H6C10H6P(CF3)2), which contains a bis(trifluoromethyl)phosphine group, was prepared in five steps from (R)-BINOL (5). As a key transformation, the unprecedented electrophilic double trifluoromethylation of the primary phosphine H2PC10H6C10H6OTf (8, OTf = triflate) was achieved using the hypervalent iodine trifluoromethylation reagent 1-trifluoromethyl-1,2-benziodoxol-3-(1H)-one (1), derived from o-iodobenzoic acid. The Pd dichloride complex of this ligand [PdCl2(Ph2PC10H6C10H6P(CF3)2)-κ2P,P] (10) shows the P(CF3)2 group with a high degree of pyramidalization at the P atom and a relatively short Pd-P bond (2.2230(4) Å), both features being indicative of the strong s-character of the P lone pair.
