Reactivity and Electronic Structure of Trigonal Planar Carbido Complexes

点击翻译按钮获取中文摘要

The first transition metal complexes containing trigonal planar carbide ligand have been synthesized, and their reactivity has been studied. The carbide ligand showed a diverse array of reactivity leading to carbon-carbon bond formation on the multimetallic site. In addition, a carbene-like electronic structure of these carbide complexes has been established. These results contribute to understanding of carbon-carbon bond forming processes on heterogeneous transition metal catalyst surfaces and to future development of new carbene compounds containing transition metal fragments as substituents(the metallocarbenes).
