Abstract
Cationic complexes of rhodium with binaphthophosphepine 1 (Ph-BINEPINE), an axially chiral binaphtalene-core monodentate P-donor ligand (Figure 1), [Rh(nbd)((S)- (Ph-BINEPINE))2]+X-, where X-= BF4-, CF3SO3-and BarF-, have been prepared. These complexes have been tested as catalyst precursors in the asymmetric reduction of α,β- unsaturated acid derivatives by both molecular hydrogen and formic acid as a hydrogen donor source.File | Dimensione | Formato | |
