4 one: Palladium‐catalyzed carbonylation initiates a highly regioselective triazolesynthesis. In this four‐partner protocol, the aryl halide, amidine, and hydrazine partners are easily varied, allowing the synthesis of fullysubstituted1,2,4‐triazoles in a modular fashion. This methodology is demonstrated with the synthesis of druglike and/or pharmaceutically relevant molecules such as deferasirox
