実験手順

Thirty-eight grams (0.50 mole) of carbon disulfide was added with stirring at 10° - 20° C to a mixture of 500 g. isopropanol and 50.5 g. (0.50 mole) triethylamine. To this solution was added 70.5 g. (0.50 mole) of spiro(cyclohexane-1,2'-oxazolidine) [preparation described by A. Cope and E. Hancock, J. Am. Chem. Soc. 64, 1503 (1942)] followed by 46.0 g. (0.25 mole) of anhydrous zinc acetate. The reaction mixture was stirred 4 hours at room temperature. After overnight standing, the precipitate was filtered to give 97.4 g. of the desired carbodithioate melting at 198° - 200° C (decomp.). A sample, dissolved in hot dimethylsulfoxide and precipitated by addition of methanol, melted at 212° - 213° C and had the following analysis: Found: C, 42.80; H, 5.41; N, 5.75; Zn, 12.90%. Calcd for C18H28N2O2S4Zn. C, 43.43; H, 5.63; N, 5.63; Zn, 13.15%.
