Phosphine-borane complexes; direct use in asymmetric catalysis
Résumé
An easy and soft method of decomplexation of phosphine-borane complexes, by DABCO, allows its use in asymmetric catalytic hydrogenation of double bonds with metal phosphine complexes. Easy decomplexation of phosphine-borane complexes has been shown by obtention of diphenylphosphinoacetaldehyde 2 and by using of DIOP-borane complex 7 in asymmetric catalytic reaction.
