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.
