acylselenoureas react with silver(I) oxide to form tetranuclear silver(I) complexes containing the deprotonated acylchalcogenourea ligands bound to the silver atoms through the chalcogen and oxygen atoms. These tetrasilver(I) species react with either 4 or 8 equiv. of a phosphine to afford either dinuclear silver(I) phosphine complexes or tetrahedral silver diphosphine complexes. In these compounds, the acylchalcogenourea

Copper(I) complexescontaining 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) complexescontaining N‐heterocyclic carbenes as well as tetrahedral bis(phosphane) copper(I) compounds

N-heterocyclic carbene complexes containing monoanionic acylchalcogenourea (chalcogen = S, Se) ligands was prepared and characterised by various spectroscopic methods and X-ray diffraction. The compounds were conveniently accessible in good yields through a one-pot reaction involving [AuCl(tht)] (tht = tetrahydrothiophene), the imidazolium salt and the acylchalcogenourea in the presence of excess base. The X-ray

acylchalcogenoureas. Imidazoliumsalts however did not react with the ammine complex directly. They were accessible from the reaction of the parent dimer with the azolium salts in the presence of base. X-rax structures of several examples are reported and DFT calculations were used to elucidate the electronic structure of the ylide ligand and the bonding interactions with the palladium atom.

compounds were fully characterised by spectroscopic methods and, in the case of compounds 1, 5 and 8, by single crystal X-ray diffraction. The compounds consist of a gold atom bound in linear fashion to the phosphine ligand and the selenium atom from the deprotonated acylselenourea. These complexes thus represent the first examples of acylselenoureato metal compounds in which the ligands do not adopt the
