A general method for synthesis of the variously substituted nitroalkenes via ethylenediaminium trifluoroacetate (EDA-TFA)-catalyzed condensation of nitroalkanes with aryl aldehydes is described. Various aminium salts of ethylenediamine with different acids as well as aminium salts of trifluoroacetic acid with different amines were examined as catalysts, and various solvents were also tested for the reaction. It was found that EDA-TFA is obviously more effective than other aminium salts, and dimethylsulfoxide (DMSO) is better than other solvents. In presence of 5 mol% of EDA-TFA as the catalyst, one-pot reaction of aryl aldehydes with various nitroalkanes in DMSO efficiently afforded variously substituted nitroalkenes in 82%~96% yields.
