Abstract:  l-(5-Nitro-2-furyl)-2-[5-(4-X-phenyl-2-furyl)]ethylenes where  X = H, СНз, CI, Br, COOC2H5, and NO2 were synthesized from 5-(4-X-phenyl)-2-fural deny des and 5-nitrofurfurylphosphate. The olefin-forming reagent, hitherto unknown 5-nitrofurfurylphosphate was prepared from 5-nitrofurfuryl bromide and triethyl phosphite using the conditions of Arbuzov reaction.
