  Camphorquinone: a new and efficient oxidant for the preparation of 2-thio-substituted benzothiazoles from alcohols by oxidation-reduction condensation

  摘要：

  A convenient one-pot procedure for the preparation of various 2-thio-substituted benzothiazoles from alcohols and benzothiazole-2-thiol utilizing camphorquinone-mediated oxidation-reduction condensation is disclosed. The condensation between benzothiazole-2-thiol and alkyl diphenylphosphinites, generated in situ from alcohols and chlorodiphenylphosphine, proceeded smoothly in the presence of camphorquinone to furnish the corresponding benzothiazoles in good to moderate yields.[GRAPHICS].

  A new and efficient method has been developed for the synthesis of thioethers from carboxylates and thiols. The reaction proceeds via a Fe(III)-catalyzed direct displacement of carboxylates from benzylic or allylic esters by heterocyclic thiols. Short reaction times, good to excellent yields of products, and few side reactions are the significant features of the new protocol.

  已经开发了一种新的有效方法，用于从羧酸盐和硫醇合成硫醚。该反应通过杂环硫醇通过Fe（III）催化的羧酸酯从苄基或烯丙基酯直接置换而进行。新协议的显着特点是反应时间短，产品收率好至极好，副反应少。

  A series of HSO4- functionalized ILs was synthesized and used as efficient, green, and metal-free catalysts for benzylation. Notably, the catalytic system has wide substrate scopes and the ionic liquid catalysts were applied to investigate three different types of nucleophiles to give the desired benzylation products with moderate to excellent yields.
