Versuchsvorschrift

β-Nitrostyrene (14.9 grams, 0.10 mole) was added in portions to a stirred mixture of piperidinium 1-piperidinecarbodithioate (24.6 grams, 0.10 mole), and carbon disulfide (7.6 grams, 0.10 mole) in methanol (200 ml.). During the addition, the reaction temperature was 25° C.-29° C. After the addition of β-nitrostyrene, the reaction mixture was cooled to 8° C., and the precipitated product was filtered off, washed with water, and dried in air. The yield of product melting at 85° C.-87° C. (prior sintering) was 29.0 grams (93%). Repeated recrystallizations without heating from methylene chloride-hexane and methylene chloride-methanol solutions gave pure α-(nitromethyl)benzyl 1-piperidinecarbodithioate melting at 86° C.-90.5° C. (prior sintering).
