Highly Efficient Microwave-assisted One-Pot Synthesis of Aromatic Nitriles from Aromatic Aldehydes

Resumo

A highly efficient and environmentally benign protocol is described for the microwave-assisted one-pot synthesis of aromatic nitriles from aromatic aldehydes by the reaction with hydroxylamine hydrochloride in DMSO, which involves the intermediate formation of aldoximes and subsequent dehydration. The developed synthetic methodology can be readily accomplished with various aldehydes containing both electron-donor and electron-acceptor groups, providing excellent yields of the target products in shorter reaction times (1–2 min) compared to previously reported methodologies.
