Gold(I) complexes bearing ring-fused benzoxazine-derived triazolylidenes and their use in C–N bond-forming processes

We report the synthesis and full characterization of a novel series of ring-fused benzoxazine-derived triazolium salts (1a–c) and their corresponding triazolylidene gold(I) complexes (2a–c). All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and mass spectroscopy and in the case of triazoliums 1a and 1b by single-crystal X-ray diffraction. The new triazolylidene gold complexes (2a–c) were tested as precatalysts in the hydroamination and hydrohydrazination of terminal alkynes employing aniline derivatives and hydrazine as nitrogen sources, respectively.

Visible-Light-Promoted AuI to AuIII Oxidation in Triazol-5-ylidene Complexes

Reaction of triazolium precursors [MIC(CH2)n- H+]I? (n=1–3) with potassium hexamethyldisilazane (KHMDS) and AuCl(SMe2) generates the gold(I) complexes of the type MIC(CH2)n?AuI. Visible light exposure of the latter complexes promotes a spontaneous disproportionation process rendering gold(III) complexes of the type [{MIC(CH2)n}2?AuI2]+I?. Both the AuI and AuIII complex series were tested in the catalytic hydrohydrazination of terminal alkynes using hydrazine as nitrogen source.

Synthesis and Catalytic Benefits of Tetranuclear Gold(I) Complexes with a C4-Symmetric Tetratriazol-5-ylidene

The facile preparation of a C4-symmteric tetratriazolium salt and its subsequent metalation to generate a series of tetranuclear mesoionic carbene gold(I) complexes is presented. The complete structural characterization of the metallic carbenes

Ancillary ligand-free copper catalysed hydrohydrazination of terminal alkynes with NH2NH2

An efficient and selective Cu-catalysed hydrohydrazination of terminal alkynes with parent hydrazine is reported. The methodology tolerates a broad range of functional groups, allows for the synthesis of symmetrical and unsymmetrical azines, and can be extended to hydrazine derivatives and amines.
