WebStable azide-transfer agent. In the presence of an amine, carboxylic acids are converted to acyl azides which undergo a modified Curtius reaction in the presence of an alcohol to give alkyl carbamates directly. With t-butanol, the resulting t-butyl carbamates can readily be converted to the free amines with mild acid. Websodium azide was found to give benzoyl azide ( 4), as shown in Scheme 1. Although this reaction proceeded in two steps from benzoic acid (1), I thought that the acyl phosphate 6 would be temporally formed if the phosphorazidate 5 were used in place of the phosphorochloridate 2, and the acyl phosphate 6 would react in situ with the azide ion …
