Enabling the facile conversion of acyl hydrazides into N-acyl carbamates via metal-free ionic-based rupture of the N-N linkage

Herein we report the one-pot transformation of readily synthesised/easily accessed acyl hydrazides into N-acyl carbamates via an alkylation-elimination reaction sequence. A range of N-acyl carbamates are prepared in consistent yields, including those featuring protecting groups and having alkyl & aryl N-acyl functionality. The reaction conditions also tolerate a wide variety of sensitive functional groups.
