The pyridyltriazole ligand was prepared and applied as a new ligand system for the coordination towards gold(III) cations. The resulting complex showed excellent stability and effective catalytic reactivity for the Meyer–Schuster rearrangement of propargyl alcohols and sequential allene halogenation, giving α-haloenones with excellent yields and good E/Z selectivity. More importantly, by using this new gold(III) catalytic system, the challenging α-chloroenone substrates were synthesized in good yields for the first time. This work also permits the avoidance of preparing of acetate derivatives as required in the case of Au(I) catalysts and validates that the triazole gold(III) complex is an effective new catalyst for alkyne activation. (Figure presented.).

Figure presented The E-α-haloenones were prepared through a triazole-Au complex (TriA-Au) catalyzed propargyl acetate rearrangement and sequential allene halogenation. The reactions proceeded with only 1% catalyst loading, giving the challenging kinetic p
