| Abstract: | It was reported that （E）-1-（2-Nitroprop-1-Enyl） Benzenes was synthesized by a rapid and efficient environmentl friendly manner. The reaction of aldehydes with nitroethane gave the desired products in good yields under ultrasound, and explored the factors influencing synthesis of nitroolefins. The experimental results showed that the optimal reaction conditions were as follows： the raw ratio ofnitroethane and benzaldehyde was 1.6 ： 1, the appropriate dosage of catalyst was 7 %, optimal temperature was 45℃, reaction time was 5 h. |
