Synthesis of N-Heterocyclic Carbene Complexes of Manganese(I) by Coupling Isocyanide Ligands with Propargylamines and Propargylic Alcohols§

A variety of N-heterocyclic carbene (NHC) complexes of general formula fac-[Mn(NHC)(CO)3(bipy)]+ have been prepared by reaction of the manganese(I) isocyanide complexes fac-[Mn(CNR)(CO)3(bipy)]+ with propargylamines and propargylic alcohols and characterized by spectroscopic and X-ray diffraction methods.
