Versuchsvorschrift

95 2/10 g. of 2-trichloromethyloxazolidine (preparation described by W. Ruske and I. Hartmann, J. Prakt, Chem. 18, 146 (1962)) was dissolved in a mixture of 300 ml isopropanol, and 50.5 g. (0.50 mole) of carbon disulfide was added dropwise followed by 43.9 g. (0.25 mole) of anhydrous zinc acetate. The reaction mixture was heated for 2 hours at 45° - 50°C, cooled to room temperature, and diluted with 1 liter water; the precipitated product was filtered, washed thoroughly with water and dried in vacuo to give 86.3 g. of the crude product, melting at 193° - 195°C (decomp.). Hot benzene extractions of the crude product gave 38 g. of the desired carbodithioate sintering at 208°C, and melting 213° - 216°C (decomp.). It had the following analysis:
