ResumoThis communication describes the activation of CO2 at the Ru pincer complex (PNN)Ru(H)(CO) (PNN = 6-(di-tert-butylphosphinomethylene)-2-(N,N-diethylaminomethyl)-1,6-dihydropyridine). The reaction proceeds to completion within minutes at room temperature to form a C–C bond between the pincer ligand and the electrophilic carbon atom of CO2. The characterization of both the kinetic and thermodynamic products of CO2 activation and the reversibility of this C–C bond formation are discussed.
