OLEFIN METATHESIS INITIATORS BEARING THIAZOL-2-YLIDENE LIGANDS

摘要

This invention relates to olefin metathesis catalysts general formula (I): having a thiazol-2-ylidene ligand of general formula (II): The catalysts have been found to be particularly good initiators of (a) ring-closing metathesis reactions used to prepare tetra-substituted cyclic olefins, and (b) cross-metathesis reactions used to prepare tri-substituted and di-substituted olefins.
