| titleOfInvention | PROCESS FOR PREPARING CYANIMIDODITHIOCHOKENOEENESTERS |
| abstract | The invention relates to a process for the preparation of Cyanimidodithiokohlensaeureestern of the general formula III, in which R 1 is alkyl, alkenyl or aralkyl, R 2 aryl or hetaryl, which may optionally be substituted andX oxygen or sulfur. According to the invention, monoester potassium salts of the general formula I are first of all chloromethylated with a 20-30-fold molar excess of bromochloromethane in the presence of 0.5 to 2 mol% of a phase transfer catalyst such as triethylbenzylammonium bromide at temperatures between 30C and 60C, and the resulting chloromethyl cyanimidodithiocarbonate the general formula II then reacted with alkali metal thiolates or phenolates. Formulas (I), (II) and (III) |
