ZHOU Jian feng 1, ZHOU Ju feng 2, ZOU Zheng cai 2, FENG Jun cai 2 (1.Department of Chemistry, Huaiyin Teachers College, Huaian,223001 ,China) (2.Department of Chemistry, Nanjing University, Nanjing,210093,Nanjing)  
A series of 1,4 bis(3 aryl 3 oxo 3 propenyl)benzenes (3) and 1,4 bis(2,2 diethoxycarbonyl ethenyl)benzene dervatives (5) were synthesized from 1,4 benzendialdehydes(1), acetophenone(2) or diethyl malonate(4) by the condensation reacion under microwave irradiation. The reactions were completed in 1 8 min with good yields and easy work up.
