| titleOfInvention | A kind of method preparing adjacent diphenyl disulfide phenol |
| abstract | The present invention provides a kind of method preparing adjacent diphenyl disulfide phenol.With metallic sodium, ethyl mercaptan and adjacent two halobenzenes as initiation material; by controlling the molar ratio of reactant; utilize the nucleophilic displacement of fluorine ability that ethyl mercaptan sodium is stronger; at polar solvent N; replacing two halogen atoms of adjacent two halobenzenes in N dimethylformamide completely, high productivity obtains 1,2 diethyl sulfenyl benzene; then the reduction at metallic sodium Yu naphthalene carries out the deprotection of sulphur atom, generation target product neighbour's diphenyl disulfide phenol the most quantitative after hydrochloric acid is acidified.The preparation method of the present invention is simple, easy to operate, low price, and productivity is high, is with a wide range of applications in fine chemistry industry and pharmaceuticals industry. |
