文摘
A series of N-heterocyclic carbene (NHC)AgCl complexes [NHC = SIMes (1), IPr (2), SIPr(3), IPrMe (4), IMe (5), ICy (6), IAd (7), IsB (8), IDD (9), and TPh (10)] have been synthesizedthrough reaction of the imidazolium chloride salts with Ag2O or by direct metalation of thecorresponding imidazol-2-ylidene carbene in the presence of AgCl. All silver(I) complexes[(SIMes)AgCl] (11), [(IPr)AgCl] (12), [(SIPr)AgCl] (13), [(IPrMe)AgCl] (14), [(IMe)AgCl] (15),[(ICy)AgCl] (16), [(IAd)AgCl] (17), [(IsB)AgCl] (18), [(IDD)AgCl] (19), and [(TPh)AgCl] (20)have been spectroscopically and structurally characterized. The structure of these silvercomplexes is dependent on the halide and the solvent used for the synthesis. Adjusting theseparameters has led to the previously reported complex, [(IMes)2Ag]+[AgCl2]- (21), and to anew silver complex, [(IMes)2Ag]+2[Ag4I6]2- (22).
