Nitroethane → 1-Methylsulfanyl-4-(2-nitro-propenyl)-benzene

Participants

Reaction Steps

The intermediate 1-[4-(methylthio)phenyl]-2-nitro-1-propene was prepared as follows: [U.S. Pat. No. 3,117,160, Example V]; a mixture containing 15.2 g of 4-(methylthio)benzaldehyde, 7.5 g of nitroethane, 0.73 g of n-butylamine and 40 ml of absolute ethanol was refluxed with stirring for 21 hours and the solvent then removed by distilling in vacuo. The residue was recrystallized from absolute ethanol (total volume of 60 ml) washed with a small quantity of cold ethanol and dried in vacuo at room temperature to produce 9.3 g of 1-[4-(methylthio)phenyl]-2-nitro-1-propene, m.p. 74°-76° C.
