First examples of phosphoric anhydride mediated O- and N-acylation

Abstract

It was shown that phosphoric anhydride can be used for the synthesis of esters and amides of carboxylic acids when they react with compounds containing hydroxyl and primary amino groups. A new method was proposed for obtaining paracetamol. An example of the reverse reactivity of these nucleophilic centers located in para -aminophenol molecule was revealed.
