Abstract
The reaction of [M(triphos)OTf](OTf) (M = Pd, Pt; triphos = (Ph 2PCH 2CH 2) 2PPh; OTf = triflate) with one equivalent of a diphenylphosphinomethylamine ligand (P Ph2N Ph(R), R = Ph or Me) leads to the formation of the M(II) complexes [Pd(triphos)P Ph2N Ph(R)](OTf) 2 (1a, R = Ph; 1b, R = Me) and [Pt(triphos)P Ph2N Ph(R)](OTf) 2 (2a, R = Ph; 2b, R = Me). Complexes 1a, 1b, 2a and 2b were obtained in moderate yields and characterized by elemental analysis, 1H, 13C, 31P NMR and X-ray diffraction. The redox behavior of these complexes shows a reversible reduction wave with half-wave potentials ranging from-1.04 to-1.23 V. Electrocatalytic proton reduction studies demonstrate these complexes function as hydrogen production catalysts with turn over frequencies ranging from 120 to 200 s -1.
