The microwave-assisted synthesis of 5-arylazo-4,6-disubstituted-3-cyano-2-pyridone dyes
摘要:
A novel protocol for the rapid synthesis of pyridone colorants under controlled microwave irradiation ill a dedicated reactor is described. Short reaction times, high isolated yields. and versatility for different substrates are the advantages of the reported method. (C) 2009 Elsevier Ltd. All rights reserved.
