Cai, Dongwei’s team published research in Organic Syntheses in 76 | CAS: 126613-06-7

Cai, Dongwei published the artcile(R)-(+)- and (S)-(-)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) (phosphine, [1,1′-binaphthalene]-2,2′-diylbis[diphenyl-, (R)- and (S)), SDS of cas: 126613-06-7, the publication is Organic Syntheses (1999), 6-11, database is CAplus.

Treating 30 mmol (R)-(+)-1,1′-bi-2-naphthol with 70 mmol Tf₂O and 90 mmol pyridine in 60 mL CH₂Cl₂ gave 90% of the chiral ditriflate of the binaphthol. Reaction of 20 mmol of the latter compound with 48 mmol Ph₂PH in presence of 2 mmol NiCl₂(dppe) in 60 mL DMF containing 80 mmol DABCO gave 77% (R)-(+)-BINAP.
