Abstract
Electrochemical studies on RuH2(PPh3)(4) (1) and Ru(0)(MA)(2)(PPh3)(2) (2), the complex that is generated when RuH2(PPh3)(4) is dissolved in methyl acrylate (MA), are carried out by cyclic voltammetry (CV). The combination of electrochemical with NMR spectroscopic measurements re veals that MA undergoes oxidative addition to Ru(0)(MA)(2)(PPh3)(2) vi a cleavage of a vinylic CH bond. The resulting hydridoruthenium(II) co mplex is not stable in MA and forms presumably a complex in which a fu rther MA is inserted into the ruthenium-hydrogen bond. (C) 1998 Elsevi er Science S.A.
