3.5 ml (55 mmoles) of chloroacetonitrile were added to a refluxing solution of 11.0 g (44 mmoles) of 3,4-dichlorophenylthio(trimethyl)silane in a mixture of 25 ml of acetonitrile and 10 ml of hexamethylphosphoric triamide and the reaction was complete with 2 minutes. The residue obtained after evaporation of the acetonitrile was dissolved in ethyl acetate, and the solution was washed with water, dried and evaporated to dryness to obtain 9.30 g (93% yield) of (3,4-dichlorophenylthio)acetonitrile boiling at 127°-130° C./0.4 mm Hg and having a refractive index of nD25 =1.5920.
