Gold-isocyanide complexes XAu(RNC) (X = halide, pseudohalide, R = alkyl, aryl) and water soluble gold-carbene complexes XAuC(NHPh)[MeN(CH 2CH2O)nMe] (X = Cl, n = 1-11) have been prepared and evaluated as substrates for the direct laser writing of gold decoration onto ceramics.

μ-(1,2-Diisocyanobenzene)bis(chlorogold) (2) reacts with 1,2-diaminobenzene (1/1) to give benzimidazolin-2-ylidene(chloro)gold (3) as the only reaction product, while 1/1-mixtures of 3 and the corresponding diaminocarbene complexes (4, 6) result from the reactions of 2 with 1,8-diaminonaphthalene or two equivalents of aniline.With one equivalent of a primary amine (MeNH2, PhNH2), however, the isocyanide complexes Au(Cl)CNR (R = Me, Ph) are obtained, again together with 3.Mechanistic key steps following the primary nucleophilic attack by the amine are a novel NC-coupling of the two neighbouring isocyano functions to give a benzimidazole ring system, and the transfer of the exocyclic Au(Cl)C fragment onto the incoming amine.Accordingly, the reactions between 2 and secondary amines lead to an isolable binuclear intermediate C' (1/1) or to the carbene complexes Au(Cl) (8, 2R = (CH2)5; 9, 2R = (CH2)2)O(CH2)2; 10, R = Me; 11, 2R = (CH2)4) (1/2), respectively. 7 and morpholine give 3 and the asymmetrical diaminocarbene complex Au(Cl)- (12).
