摘要

The cyclopropanation reaction of electron-deficient olefins with Group 6 Fischer carbene complexes is a rather general and well-established process [1] that was first reported in 1970.[2] Alkoxycarbene complexes are able to transfer their carbene ligand to the C= C bond of alkenes, which are substituted by various electron-withdrawing groups (EWG).[3] α, β-Unsaturated esters, amides, or nitriles,[4] alkenyl phosphonates,[4a, c–e, g, i] alkenyl ...
