Testing new ruthenium complexes bearing chiral 1,2,4-triazol-5-ylidene- ligands as catalysts for asymmetric olefin metathesis

摘要

New ruthenium complexes bearing chiral 1,2,4-triazol-5-ylidene ligands were obtained and tested in model asymmetric metathesis reactions. Low enantioselectivity in asymmetric ring-closing metathesis (ARCM) and moderate enantioselectivity in asymmetric ring-opening/ring-closing metathesis (AROCM) was observed.
