Abstract

The chemistry of the coordinatively unsaturated hydridodiruthenium complex cation [Ru2(μ-H)(μ-CO)(CO)3(μ-dppm)2]+, 1, is described. Complex 1 adds CO to give [Ru2(μ-H)(μ-CO)(CO)4(μ-dppm)2]+, reacts with hydrogen to give [Ru2(μ-H)2(CO)4(μ-dppm)2] and H+ and, in the presence of Et3N, is an efficient catalyst for decomposition of formic acid to CO2 and H2. Complex 1 reacts easily with acetylene to give [Ru2(μ-CH[double bond, length as m-dash]CH2)(CO)4(μ-dppm)2]+, with PhCCH to give the coordinatively unsaturated alkenyl complex [Ru2{C(Ph)[double bond, length as m-dash]CH2}(μ-CO)2(CO)2(μ-dppm)2]+ which then rearranges to the isomeric, coordinatively saturated complex [Ru2(E-μ-CH[double bond, length as m-dash]CHPh)(CO)4(μ-dppm)2]+, and reacts reversibly with PhCCPh to give [Ru2{Z-C(Ph)[double bond, length as m-dash]CHPh}(μ-CO)2(CO)2(μ-dppm)2]+.
