文摘

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 Au(I)–MIC. Visible-light exposure of the latter complexes promotes a spontaneous disproportionation process rendering gold(III) complexes of the type Au(III)–(MIC)₂. Both the Au(I) and Au(III) complex series were tested in the catalytic hydrohydrazination of terminal alkynes using hydrazine as nitrogen source.
