Abstract
4-(1,1-Dimethylethyl) benzylidene-4'-methoxyacetophenone was prepared from 4-methoxyacetophenone and 4-tert-butyl-benzaldehyde by catalyst under microwave irradiation.The effect of power,time of microwave irradiation,the amount of catalyst and volume of solvent on yield were studied.The optimum reaction conditions were that the mole ratio of 4-tert-butyl-benzaldehyde to 4-methoxyacetophenone was 1 ∶1,the microwave irradiation time was 70 s with the power of 480 W;dosage of catalyst was 90 g,volume of methanol used as solvent was 100 mL.The yield was over 95%.
