Arene-ruthenium(II) complexes containing inexpensive tris(dimethylamino) phosphine: Highly efficient catalysts for the selective hydration of nitriles into amides
The catalytic hydration of nitriles into amides, in water under neutral conditions, has been studied using a series of arene-ruthenium(II) derivatives containing the commercially available and inexpensive ligand tris(dimethylamino)phosphine. Among them, best results were obtained with the complex [RuCl2(eta6-C6Me6) {P(NMe2)3}], which selectively provided the desired amides in excellent yields and short times (TOF values up to 11 400 h-1). The process was operative with both aromatic, heteroaromatic, aliphatic, and alpha,beta-unsaturated organonitriles and showed a high functional group tolerance. The stability of [RuCl2(eta6-C 6Me6){P(NMe2)3}] in water was evaluated, observing its progressive decomposition into the less-active dimethylamine-ruthenium(II) complex [RuCl2(eta6-C 6Me6)(NHMe2)] by hydrolysis of the coordinated P(NMe2)3 ligand. The X-ray crystal structure determination of the toluene complex [RuCl2(eta6-C6H 5Me){P(NMe2)3}] is also included.
