We report herein a cationic iridium-catalysed thioether-directed alkyne–azide cycloaddition reaction. Diverse 2-alkynyl phenyl sulfides can undergo cycloaddition with different azides in a regioselective fashion. The reaction features high efficiency, a short reaction time, and a broad substrate scope, providing modular access to complex S-containing triazoles.

The synthesis and characterization of the triphenylamine-capped cyclophane 3 are described. It proved to be a conformationally rigid molecular propeller, with an inwardly pyramidalized, unreactive amine.
