The reaction between the tungsten hydride complex trans-W(CMes)(dmpe)2H [1, dmpe = 1,2-bis(dimethylphosphanylethane)] and a series of electrophilic transition metal carbonyl compounds has been investigated, to explore the generality of W-H reductions of coordinated CO. Hydride transfer to the mononuclear [Fe(CO)5], and to the dinuclear [Re2(CO)10], yields the neutral heterobimetallic formyl complexes trans-W{(μ-OCH)Fe(CO)4}(CMes)(dmpe)2 (2) and trans-W{(μ-OCH)Re2(CO)9}(CMes)(dmpe)2 (3a), respectively. In the latter case, after one week at room temperature, 3a is smoothly converted into the stable ionic complex [W(CMes)(CO)(dmpe)2]+[Re2(CO)9H] - (3b). Reaction with the cluster [Ru3(CO)12] results in the formation of an unstable formyl complex, which undergoes a direct rearrangement at -20 °C to produce the ionic complex [W(CMes)(CO)(dmpe)2]+[Ru3(CO) 11H]- (4) as the final product. The molecular structure of 4 was unambiguously established by single-crystal X-ray diffraction.
