Testing New Ruthenium Complexes bearing Chiral 1,2,4-Triazol-5-ylidene Ligands as Catalysts for Asymmetric Olefin Metathesis

Abstract

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.
