Ruthenium complexes with an N-heterocyclic carbene NNC-pincer ligand: preparation and catalytic properties

1-Methyl-3-(2-((pyridin-2-ylmethylene)amino)ethyl)-1H-imidazol-3-ium bromide was prepared and used as an N-heterocyclic carbene NNC-pincer ligand precursor. Depending on the coordination strategy, a monometallic [Ru(NNC)(CO3)(PPh3)] complex, or the [Ru(μ-Cl)(NNC)]2(2Cl−) dimer, was obtained. A di-si...
