资源简介：
Reactions of a series of unsymmetrically substituted N-heterocyclic carbene ligands with Ru3(CO)12 afforded a variety of mononuclear (1, 2), trinuclear (3, 4, 5, and 5′), and tetranuclear (6, 7) ruthenium complexes via intramolecular ruthenium-mediated sp2 and sp3 C–H bond activations. Complexes 6 and 7 include an octahedral cluster skeleton consisting of four ruthenium atoms and two metalated carbon atoms. The formation of this type of ruthenium clusters is proposed to involve the initial C–C double-bond migration and subsequent sp2 C–H bond activations. All new complexes were fully characterized, and the molecular structures of 1, 2, 5, 6, and 7 were determined by X-ray diffraction analysis.
