A general synthesis of phosphine–borane complexes proceeding in high yield in a safe, green process from borane generated in situ from sodium borohydride is described. The procedure also allows simultaneous carbonyl reduction and phosphine–borane formation on air-sensitive bulky phosphine derivatives.

organopalladium cross-coupling chemistry. Prepared via a direct double Michael addition of a monoalkyl- or arylphosphine to phorone followed by a Wolf-Kishner reduction, phosphorinanes are relatively inexpensive to manufacture and allow modification of one of the alkyl moieties permitting steric and electronic fine-tuning of the ligands.

combination with an improved preparation of the monotriflate, is effective for 1,1′-binaphthalene-2-ols containing unsubstituted or electron-poor aryl or benzyl 2′-substituents. An alternative procedure, using a potentially hemilabile-bidentate phosphinan-4-ol ligand, is superior for products containing neopentyl or electron-rich aryl 2′-substituents. The obtained binaphthyl alcohols represent potentially
