Copper(I) Complexes with Anionic Acylthio- or Acylselenourea Ligands and N-Heterocyclic Carbenes or Phosphanes: Copper(I) Complexes with Anionic Acylthio- or Acylselenourea Ligands and N-Heterocyclic Carbenes or Phosphanes

Copper(I) complexes containing acylthio- and selenoureato ligands can be accessed either by transmetallation from the corresponding silver compounds or by direct reaction of the acylthio/selenourea with a copper(I) precursor in the presence of base. Several examples of tricoordinate organocopper(I) complexes containing N-heterocyclic carbenes as well as tetrahedral bis(phosphane) copper(I) compounds are reported with their spectroscopic and structural characterization.
