反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of phenacyl dimethyldithiocarbamate (12.0 grams, 0.050 mole), formaldehyde (4.1 grams of 37% aquoeus solution, 0.050 mole), carbon disulfide (1.9 grams, 0.025 mole), and dimethylammonium dimethyldithiocarbamate (8.3 grams, 0.050 mole) in methanol (50 ml.) was stirred and heated at 38° C.-40° C. for 2.5 hours. The reaction mixture was then cooled to 0° C. and the precipitated product was filtered off, washed with cold methanol and dried in air. The yield of product melting at 106° C.-108° C. was 17.6 grams (94%). Repeated recrystallization from methylene chloride-methanol and acetone-2-propanol solution without heat gave pure 1-benzoylethylene dimethyldithiocarbamate melting at 106° C.-109.5° C. The structure was determined from the infrared spectrum and elemental analysis. heated at 38° C.-40° C. for 2.5 hours the precipitated product was filtered off washed with cold methanol dried in air recrystallization from methylene chloride-methanol and acetone-2-propanol solution without heat
