| titleOfInvention | A kind of method for preparing heterocyclic o-iodosulfide |
| abstract | The invention discloses a method for preparing heterocyclic o-iodosulfide. Heterocyclic thiophenol and o-diiodobenzene are used as substrates to react in a solvent in the presence of metal hydrides to prepare heterocyclic o-iodosulfide. The traditional metal-free C‑S coupling reaction requires pre-preparation of active species such as iodonium and sulfonium precursors, which is costly and difficult to prepare. In the present invention, under the action of sodium hydride, o-diiodobenzene can react with thiophenol to synthesize heterocyclic o-iodosulfide. The raw materials of ortho-diiodobenzene are cheap and easy to obtain, and the reaction is mild; at the same time, heterocyclic ortho-iodothioethers can be extensively transformed in the next step to prepare various 1,2-disubstituted benzenes, which provides a great opportunity for the synthesis of complex natural products and drug molecules. An easy way. |
