Abstract

Dirhodium (II) complexes are highly popular in organic synthesis due to their remarkable efficiency in the generation of carbenoids from diazo compounds.[1, 2] These complexes contain a RhÀRh bond, two axial ligands, and four bridging ligands which control the electrophilicity of the catalyst and, in some cases, provide a mechanism for inducing asymmetry. The two axial ligands (normally solvent molecules) form a weaker bond with ...
