| titleOfInvention | A kind of synthetic method of thiosulfonic acid esters compound |
| abstract | The invention belongs to organic synthesis field more particularly to a kind of synthetic methods of thiosulfonic acid esters compound.The present invention provides a kind of synthetic method of thiosulfonic acid esters compound, are as follows: sulfonyl hydrazines compound, phenyl-sulfhydrate compounds, oxidant and catalyst, which are dissolved in solvent, to react, and purifies to obtain thiosulfonic acid esters compound；Oxidant is tert-Butanol peroxide, and catalyst is any one or more in sodium iodide, potassium iodide, ammonium iodide, elemental iodine and tetrabutylammonium iodide.It can be obtained through measuring, thiosulfonic acid esters compound prepared by technical solution provided by the invention, no side reaction occurs, and yield is up to 84%~100%, high conversion rate；Meanwhile oxidant used in the present invention and catalyst, it is environmentally friendly compound, does not will cause environmental pollution, reaction temperature is low, is suitable for industrial large-scale promotion；It solves in the prior art, the synthesis of asymmetric thiosulfonic acid esters compound is big to environmental disruption, can not be applied to industrial defect. |
