Tetra-n-butylammonium Iodide Catalyzed C-H Azidation of Aldehydes with Thermally Stable Azidobenziodoxolone

Tetra-n-butylammonium iodide can efficiently catalyze direct azidation of aldehyde C-H bonds with thermally stable azidobenziodoxolone at room temperature. Compared to conventional methods, which require excessive amounts of highly explosive azide sources, this is a safe and convenient procedure.
