A general acyl azide
Acyl azides are carboxylic acid derivatives with the general formula RCON3.
Preparation
Alkyl or aryl acyl chlorides react with sodium azide to give acyl azides.[1][2]
They can also be synthesized from various carboxylic acids and sodium azide in presence of triphenylphosphine and trichloroacetonitrile catalysts in excellent yields at mild conditions.[3] Another route starts with aliphatic and aromatic aldehydes reacting with iodine azide which is formed from sodium azide and iodine monochloride in acetonitrile.[4]
Uses
Acyl azides are used as chemical reagents. On Curtius rearrangement acyl azides yield isocyanates.[5][6][7][8]
Acyl azides are also formed in Darapsky degradation,[9][10][11][12][13]
