摘要：
The first ruthenium olefin metathesis catalyst bearing a four-membered N-heterocyclic carbene (5) was synthesized and characterized by NMR spectroscopy and X-ray crystallography. The synthesis of a (carbene)carbonylrhodium complex (6) was also reported, allowing the study of the electronic properties of this new carbene ligand. The complex 5 was screened toward different olefin metathesis reactions, and it showed a slow reactivity.
