Nitroolefin is a common and versatile reagent, synthesis of which from aldehydes/ketones, α, β-unsaturated carboxylic acids or olefins is generally limited by the high cost of raw materials in industrial processes in the future. Herein, an alternative and economical protocol for the synthesis of nitroaromatic olefins directly from easily available arylethanes with barium nitrate using Cu/Ag as cocatalyst and ammonium persulfate as the terminal oxidant is reported. Additionally, 1,1-diphenylethanes, phenylethanes, 4-ethyl-1,1'-biphenyl and ethylnaphthalenes were suitable substrates for the current dehydrogenative nitration, and provided E-nitroaromatic olefins in moderate to good yields.

Key words: nitroaromatic olefins, arylethanes, barium nitrate, dehydrogenative nitration, ammonium persulfate
