Reactions of iron and cobalt complexes containing bis(imino)-N-heterocyclic carbene complexes are discussed.  Comparison of these complexes with bis(imino)pyridine complexes are made for the hydrogenation of olefins and for [2+2] cycloaddition reactions of alkenes.  Consistent with the bonding in these complexes is the isolation of products that involve the participation of the N-heterocyclic carbene carbon atom.   Mechanistic implications for these findings will be discussed along with future applications in catalysis.
