Old Selenium Heterocycles Revisited: Synthesis, Spectroscopic, and Structural Characterization of<i>N</i>-Acyl-1,3-selenazol-2(3<i>H</i>)-imines and 5-Acyl-1,3-selenazol-2-amines from Acylselenourea Derivatives

reaction of various selenoureas and phenacyl bromides. In the case of 1‐acyl‐3‐arylselenoureas N‐acyl‐1,3‐selenazol‐2(3H)‐imines are formed, whereas the analogous reaction with 3,3‐disubstituted 1‐acylselenoureas affords 5‐acyl‐1,3‐selenazol‐2‐amines. The compounds were characterized by NMR spectroscopy and mass spectrometry. In addition, the proposed structures were unambiguously confirmed by X‐ray diffraction

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
