Microwaves, supported-reagents and parallel synthesis: isocyanide and ester synthesis.

Stefano Crosignani1, Delphine Launay, Bruno Linclau, Mark Bradley.   

Abstract

The benefits of microwave irradiation are described for a number of important reactions such as amid and ester formation and dehydration of formamide to the corresponding isonitriles. Not only were reaction times dramatically reduced but the transformations were less prone to side reactions and decomposition.
