실험 절차

More specifically, 10 ml of ethanol solution containing benzyl chloride (4.8 g, 38 mmol, Mw. 126.58) was added dropwise into 50 ml of ethanol solution containing sodium N,N-diethyldithiocarbamate trihydrate (10.3 g, 46 mmol, Mw. 225.31) in nitrogen atmosphere at 0° C. After agitating the reaction solution for 23 hours at room temperature, 150 ml of water was added and extracted by diethylether (200 ml×3 times). The organic layer was washed with water (100 ml×3 times) and was dried by sodium sulfate. Solvent was distilled away under reduced pressure using an evaporator so as to obtain benzyl N,N-diethyldithiocarbamate (colorless liquid). Yield point was 17.6 g (yield: 93%), 1H-NMR: δ7.407 ppm to 7.271 ppm (m, 5H, Ar—H), δ4.540 ppm (s, 2H, Ar—CH2S), δ4.082 ppm to 4.012 ppm (q, 2H, —N—CH2—), δ3.763 ppm to 3.692 ppm (q, 2H, —N—CH2—), δ1.311 to 1.252 ppm (m, 6H, —CH2—CH3).
