| Abstract: | In the presence of solid superacid catalyst and by means of microwave irradiation, the synthesis of coumarin derivatives 7-hydroxy-4-methyl coumarin is conducted by the condensation of 1,3 - benzenediol and acetylacetic ethyl. The result shows that its optimum reaction conditions are as follows: 0.2mol 1,3-benzenediol, 0.2mol acetylacetic ethyl, 0.5g ZrO2/SO42- solid superacid catalyst, 210W microwave power and 6 min microwave irradiation. And the yield reaches 92.5%. |
