New insights into the mechanism of asymmetric hydrogenation catalysed by monophosphonite–rhodium complexes

Abstract

The solvento complex [Rh(L)2(S)2]+ where L = tBuP(R-binaphthoxo) is shown to be in equilibrium with an η-arene dirhodium complex and only weak, monodentate binding of alkenes is observed; in addition, an intermediate Rh alkyl hydride complex containing two coordinated monophosphonites is unambiguously characterised by NMR.
