Abstract

While most metallic elements across the Periodic Table form stable chelating ß-diketiminato complexes, examples of Au(I) are conspicuous by their absence. We report here the reaction of K[HC(F₃CC==NR)₂] with AuCl(PPh₃) which provides a rare example of a thermally stable gold(I) diketiminato complex, (Ph₃P)Au[RN==C(CF₃)CH(CF₃)C==NR] [R = 3,5-C₆H₃(CF₃)₂]. The complex is highly fluxional in solution but in the solid state adopts a U-conformation. By contrast, the analogous reaction of K[HC(F₃CC==NR)₂] with CuBr(PPh₃)₃ gives the rigid 18-electron chelate complex (Ph₃P)₂Cu[?²-HC{(CF₃)C==NR}₂]
