Abstract
Abstract A coordinatively unsaturated iron-methyl complex having an N-heterocyclic carbene ligand,[Cp* Fe (L Me) Me](1; Cp*= η 5-C 5 Me 5, L Me= 1, 3, 4, 5-tetramethyl- imidazol-2-ylidene), is synthesized from the reaction of [Cp* Fe (TMEDA) Cl](TMEDA= N, N, N′, N′-tetramethylethylenediamine) with methyllithium and L Me. Complex 1 is found to activate the C [BOND] H bonds of furan, thiophene, and benzene, giving rise to aryl ...
