Abstract
We report the synthesis, isolation, and comprehensive characterization of N-heterocyclic carbene gold xanthate (NHC–Au–X, X – xanthate) complexes. These easily accessible complexes demonstrate significant versatility as photocatalysts, facilitating [2+2]-cycloadditions, and as π-catalysts in the intramolecular hydroxylation of allenes and hydrohydrazination of alkynes.
