N,N′-Dialkyl- andN-Alkyl-N-mesityl-SubstitutedN-Heterocyclic Carbenes as Ligands in Grubbs Catalysts
Various symmetrically and asymmetrically substituted N-heterocyclic carbene (NHC) ligands bearing aliphatic nitrogen-containing side groups have been synthesised. In our attempts to isolate the corresponding second-generation Grubbscatalysts, we were unsuccessful when using the symmetrical aliphatic NHC ligands. For the asymmetrical ligands bearing an aliphatic moiety on one side and an aromatic mesityl
