diethylcarbamodithioic acid

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Preparation of triethylammonium salt of diethyl dithiocarbamate is as follows: 76 grams (1 mole) carbon disulfide and 101 grams (1 mole) triethylamine are mixed at 10° C. under nitrogen. To the mixture is added in slowly 80.5 grams (1.1 mole) diethylamine drop wise and maintain the temperature below 30° C. Then the mixture is heated to 50° C. for 1 hour. The solution is then stripped out under vacuum to remove the excess amine and for the removal of low volatiles to obtain final product. The acid number (normally below 30) is measured to check the acidity. The product purity (ranging between 85-95%) is measured by LC-MS and NMR. maintain the temperature below 30° C to remove the excess amine for the removal of low volatiles

Procedure: 4-Chloromethylbenzoic acid (4 g, 0.0234 mol, 1.0 equiv.) was dissolved in warm ethanol (20 mL). Diethyldithiocarbamic acid, sodium salt trihydrate (7.92 g, 0.0328 mol, 1.5 equiv.) was also separately dissolved in warm ethanol (20 mL). The solution of the carbamic acid was then added to the solution of the carboxylic acid. The resulting mixture was then stirred at 40-50° C. for 2 h, then stirred overnight at r.t. The reaction mixture was then evaporated to dryness and separated between dichloromethane and brine. The aqueous layer was separated and acidified with conc. HCl to a pH value of 2. The precipitate that formed on acidification was filtered and air-dried to give a white solid, 4.1 g (yield 62%). 1H NMR (acetone-d6, 400 MHz) δ 1.26, br. s, 6H, 2×CH3; 3.82, br. s, 2H, CH2N, 4.5, br. s, 2H, CH2N, 4.67, s, 2H, CH2S; 7.56 (d, J=8 Hz, 2H, aromatic); 7.98 (d, J=8 Hz, 2H, aromatic) ppm. 13C NMR (acetone-d6, 400 MHz) δ 11.78, 12.98, 41.53, 47.55, 50.45, 130.26, 130.45, 130.69, 143.74, 167.40, 194.94 ppm. stirred overnight at r.t The reaction mixture was then evaporated to dryness separated between dichloromethane and brine The aqueous layer was separated The precipitate that formed on acidification was filtered air-dried to give a white solid, 4.1 g (yield 62%)
