1-Acyl triazenes can be prepared by acid-catalyzed hydration, gold/iodine-catalyzed oxidation, or oxyhalogenation of 1-alkynyl triazenes. Crystallographic analyses reveal a pronounced effect of the acyl group on the electronic structure of the triazene function. 1-Acyl triazenes display high thermal stability, and only moderate sensitivity toward hydrolysis. They are compatible with basic and oxidative conditions, allowing subsequent transformation. Under acidic conditions, 1-acyl triazenes act as acylation reagents.
