  摘要：

  披露了一种新颖的选择性合成路线，用于在芳香化合物上引入初级烷基团。该合成路线基于在芳香取代反应中生成的硫正离子物种，这些硫正离子物种是从醛和硫醇原位生成的，从而得到可以与三乙基硅烷还原的苯甲基硫醚。

  Novel selective synthesis route to introduce primary alkyl groups on aromatic compounds is disclosed. The synthesis route is based on electrophilic aromatic substitutions of thionium ion species that are generated in-situ from aldehydes and thiols, affording benzyl sulfide that can be reduced with triethylsilane.

• Reductive Alkylation of Arenes by a Thiol-Based Multicomponent Reaction

  A simple and highly chemo- and regioselective method for introducing primary alkyl substituents into aromatic compounds was developed. The method is based on an electrophilic aromatic substitution of an aldehyde, promoted by a thiol, to afford 1-(alkylthio)alkylarenes, which can either be reduced in situ with triethylsilane or reacted further. This multicomponent reaction enables the direct introduction of both aromatic and linear and branched aliphatic alkyl groups into arenes. The above one-pot protocol may be performed in air and in the presence of water and is compatible with various functional groups.
