Abstract

Dimethyl acetylenedicarboxylate is shown to rearrange at a diruthenium centre to give a μ-C[double bond, length half m-dash]C(CO2Me)2 vinylidene complex in high yield via a 1,2-CO2Me shift within a diruthenacyclopentenone species, a transformation proposed to occur via a zwitterionic μ-cyclopropenyl intermediate stabilised by the Cp* ligand.
