Synthesis of Hydrazines via Radical Generation and Addition of Azocarboxylic tert-Butyl Esters. | LitMetric

Synthesis of Hydrazines via Radical Generation and Addition of Azocarboxylic tert-Butyl Esters.

Org Lett

Key Laboratory of Synthetic and Natural Functional Molecule Chemistry of Ministry of Education, Department of Chemistry & Materials Science , Northwest University, Xi'an 710069 , P. R. China.

Published: April 2018

A new chemistry of azo compounds that is a radical generation and addition in situ of azocarboxylic tert-butyl esters to synthesize hydrazines has been described. The protocol provides a novel strategy for the synthesis of various hydrazines. The advantages of the transformation include broad substrate scope, benign conditions, and convenient operation.
