| Abstract: | Using NaHSO4·H2O as the catalyst,methyl salicylate,ethyl salicylate,n-propyl salicylate,iso-propyl salicylate,and tert-butyl salicylate,five important organic intermediates,were obtained in 76%~91% yields from chloroacetic acid and corresponding alcohol under microwave irradiation at 250 W for 10 min.This method has the advantages of easy manipulation,reused of the catalyst,short reaction time,and friendly to environment.All products were identified by 1HNMR and elementary analysis. |
