Facile microwave assisted decarbonylation of 4-formyl group in 5-alkyl amino substituted pyrazoles
摘要:
Facile decarbonylation of the 4-formyl group in 5-alkyl amino pyrazoles was seen when reacted with catalytic p-toluene sulfonic acid in methanol under microwave irradiation to provide parent 4-H pyrazoles in good yields. (C) 2008 Elsevier Ltd. All rights reserved.
