O-ethyl cyanomethylsulfanylmethanethioate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of bromoacetonitrile (12.4 g) and potassium O-ethyl dithiocarbonate (16.0 g) in ethanol (200 mL) were allowed to stir at room temperature for 16 hours. The reaction was diluted with water (100 mL) and the organics extracted with diethyl ether. The combined organic layers were washed twice with water, then brine and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue purified by column chromatography (silica-gel 60, 70-230 mesh) eluting with 4:6 ethyl acetate:petroleum spirit 40-60° C. to afford the title compound as a yellow oil (14.6 g, 90.7%). 1H-nmr (CDCl3) δ 1.48 (t, 3H); 3.88 (s, 2H); 4.72 (q, 2H). 13C-nmr (CDCl3) δ 13.7, 21.3, 71.5, 115.7, 209.2. the organics extracted with diethyl ether The combined organic layers were washed twice with water brine and dried over anhydrous magnesium sulfate The solvent was evaporated the residue purified by column chromatography (silica-gel 60, 70-230 mesh) eluting with 4:6 ethyl acetate
