The use of chiral non-racemic biaryl copper(I) complexes in the enantioselective cyclopropanation of a number of olefins with either ethyl or tert-butyl diazoacetate: is described. Lack of ligand acceleration and the presence of equilibrium amounts of catalytically active uncomplexed Cu(I) ions account for lowered enantioselectivity when using certain ligands.
