Acrylonitrile → 3-[(3-Bromophenyl)thio]propionitrile

참여 물질

반응 단계

3-Bromothiophenol (10 g, 52.9 mmmol) was dissolved in acrylonitrile (11.28 g, 213 mmol). Triton B (1 mL) was added, at which time the reaction mixture became exothermic and began to reflux without added heat. The mixture was allowed to cool to room temperature, poured into cold aqueous sodium hydroxide (2%; 200 mL), and extracted with diethyl ether. The organic layer was dried, filtered and evaporated to provide 12 g (93%) of 3-[(3-bromophenyl)thio]propionitrile as a tan oil; 1H NMR (CDCl3) δ7.54 (s, 1H), 7.42 (d, 1H), 7.32 (d, 1H), 7.25-7.15 (m, 2H), 3.15 (t, 2H), 2.62 (t, 2H); Mass spectrum m/z 261, 259 (M+NH4).
