Ethanol → 4-(1-Phenylethenyl)benzene-1,2-diamine

Participants

Reaction Steps

1-(4-Amino-3-nitrophenyl)-1-phenylethylene (7.7 g., 0.032 mole) was dissolved in refluxing ethanol (450 ml.). To this was added, dropwise, a solution of sodium sulfhydrate (38.5 g., 0.45 mole) in water (110 ml.). The resulting solution was refluxed overnight. The reaction mixture was diluted with water (1 l.), cooled and filtered yielding 1-(3,4-diaminophenyl)-1-phenylethylene: 5.6 g., 83% yield, m.p. 109°-110°.
