POLY-N-HETEROCYCLIC CARBENE TRANSITION METAL COMPLEXES AND N-HETEROCYCLIC CARBENE TRANSITION METAL COMPLEXES FOR CARBON-SULFUR AND CARBON-OXYGEN COUPLING REACTIONS

摘要

Methods for carbon-sulfur (C—S) or carbon-oxygen (C—O) coupling reactions are provided. The methods involve the use of a transition metal complex comprising a heterocyclic carbene ligand complexed with a transition metal. Transition metal complexes comprising a heterocyclic carbene ligand complexed with nickel are also provided. The nickel heterocylic carbene complexes may be used for C—S or C—O coupling reactions.
