Paragraph 0059-0062, (2020/08/30)
The invention discloses a synthesis method of heteroaryl thioether. Under the conditions of no catalyst, no solvent, no additive and the like, aryl halide/2-bromopyridine, thiourea and substituted benzyl bromide which are directly taken as raw materials to selectively synthesize asymmetric heteroaryl thioether in one step without using conventional organic sulfides such as mercaptan or thiophenol.The use of organic sulfides with high toxicity and heavy odor, such as mercaptan or thiophenol, is avoided, and the synthesis steps are shortened, so that the synthesis efficiency is improved, the reaction has good selectivity, and the asymmetric thioether can be preferentially obtained.

It is observed the crystal water in sodium thiosulfate pentahydrate (Na2S2O3·5H2O) can promote its multicomponent reaction with heteroaryl chlorides and alcohols, providing a facile, green, and specific synthesis of unsymmetrical heteroaryl thioethers via one-step formation of two C-S bonds under catalyst-, additive-, and solvent-free conditions. Mechanistic studies suggest that the crystal water in Na2S2O3·5H2O is crucial in generating the key thiol intermediates and byproduct NaHSO4, which then catalyzes the dehydrative substitution of alcohols with thiols to afford thioethers.

A simple and efficient method for palladium and copper co-catalyzed Markovnikov hydrothiolation of thiols to olefins or alkynes has been developed. The reaction allows olefins or alkynes bearing various functional groups to react with different thiols, pr
