| titleOfInvention | A synthesis method for 2 - sulfinyl -5 - (trifluoromethyl) - 1,3,4 - thiadiazole compounds |
| abstract | The invention belongs to the field of organic synthesis of sulfoxides. A synthesis method for 2 - sulfinyl -5 - (trifluoromethyl) - 1,3,4 - thiadiazole compounds comprises the step that: in an organic solvent or a mixture of an organic solvent and water, 2 - thioether -5 - (trifluoromethyl) -1,3,4 - thiadiazole reacts under the effect of a specific oxidizing agent and at a suitable temperature, to give 2 - sulfinyl - 5 - (trifluoromethyl) -1,3,4 - thiadiazole, wherein a catalyst can be added in the reaction to increase the reactivity, and a phase transfer catalyst can be added to increase the reaction rate. The method is simple in operation, and the reaction is safe, quick, and relatively high in yield, thus the method is suitable for industrial productions. Technical problems in conventional methods for preparing thiadiazole compounds such as a long reaction time, the use of an expensive transition metal catalyst, difficulties in catalyst preparation, poor safety, complicated operations, proneness of peroxidation, low selectivity and low yields. |
