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 solution 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°.
