Abstract

Acid azides are important intermediates as they undergo Curtius rearrangement leading to isocyanates. 2 Isocyanates are generally prepared2 in a one-pot procedure by treating the acid chloride with ammonium or metal azide without isolating the intermediate acid azide. Although alkanoyl azides are generally unstable and explode on heating, the corresponding aroyl azides are thermally stable and can be i~ olated.~ However, the preparation of aroyl ...
