Synthetic method for thioetherification and thiocarbonylation of halogenated alkane

The invention relates to the technical field of organic synthesis, in particular to a synthetic method for thioetherification and thiocarbonylation of halogenated alkane. According to the method, a 3-methylthiopropionic acid methyl ester derivative is used as a vulcanizing reagent to realize thioetherification and thiocarbonylation of halogenated alkane; IPrCuCl is used as a catalyst to realize thioetherification; in the presence of carbon monoxide, IPrCuCl and bis-salicylamide ethyl cobalt are used for co-catalysis to obtain thioester; and the vulcanizing reagent is easy to synthesize, mild in reaction condition and high in practicability. According to the invention, thiol with strong smell, high toxicity and environmental pollution is not used, good functional group tolerance and excellent yield and purity are achieved, harsh reaction conditions are not needed, and the method is suitable for industrial production. 本发明涉及有机合成技术领域，具体涉及一种卤代烷烃硫醚化和硫代羰基化的合成方法；利用3-甲硫基丙酸甲酯衍生物作为硫化试剂，实现卤代烷烃的硫醚化和硫羰基化；利用IPrCuCl做催化剂，实现硫醚
