A solution of dimethylammonium dimethyldithiocarbamate (16.6 grams, 0.10 mole), carbon disulfide (7.6 grams, 0.10 mole), benzaldehyde (21.2 grams, 0.20 mole), and nitromethane (9.2 grams, 0.15 mole) in 95% ethanol (50 ml.) was allowed to stand at 23° C. for several days. The resulting precipitate was filtered off, washed with cold 95% ethanol, and dried in air. The solid product, which melted at 101° C.- 102° C., was recrystallized from 2-propanol to give α-(nitromethyl)benzyl dimethyldithiocarbamate melting at 105° C.-106° C. The structure was determined from infrared and nuclear magnetic resonance spectra and elemental analysis.
