An effective synthesis of carbamoyl azides directly from primary alcohols using iodobenzenedichloride in combination with sodium azide has been developed. Moreover, the same regent combination was also efficient for the oxidation of secondary alcohols to the corresponding ketones.

Aliphatic and aromatic aldehydes can be converted to acyl azides by treatment with iodine azide at 0-25 degrees C. If the reaction is performed at reflux Curtiusrearrangement occurs and carbamoylazides are obtained in 70-97% yield from the aldehyde. The reaction was shown to have a radical mechanism.

An efficient KI catalyzed nitrogenation of aldehydes and alcohols for the direct synthesis of carbamoylazides and ureas via a radical process has been developed. The simple operating procedures, the readily available starting materials including aldehydes, alcohols and amines, as well as the utility of the products all make this strategy very attractive.
functionalization of ketones through double C–C bond cleavage strategy has been disclosed. This reaction provides a mild, practical method toward carbamoyl azides, which are versatile intermediates and buildingblocks in organicsynthesis. Based on relevant mechanistic studies, a unique and plausible C–C bond and N–O bond cleavage process is proposed, where the oxyamination intermediate plays an important

efficient copper-catalyzed synthesis of carbamoyl azides directly from aldehydes has been developed. Both aromatic aldehydes and aliphatic aldehydes, together with other commercially available reactants, can be used as substrates in this radical relay reaction. Broad substrate scope, simple operation, readily available reagents, and good functionality tolerance make this method very attractive.
