A relative synthetic strategy toward intermolecular oxidative C −Chalcogen bond formation of alkanes has been illustrated using both Cu(II) assisted vs Cu(II) free conditions. This led to construction of a comparative study of hydrocarbon benzylic and 2∘/ 3∘-cycloalkyl moieties bond sulfenylation and selenation protocol by the chalcogen sources, particularly sulfur and selenium, respectively. In addition, this protocol disclosed the auspicious formation of sp3 C−S coupling products over leading the sp3 C−N coupling products by using 2-mercaptobenzothiazole (MBT) substrates.
一种相对综合的策略已被阐述,用于
烷烃分子间氧化性C-
硫族元素键的形成,采用了Cu(II)辅助与无Cu(II)条件两种情况。这使得能够构建一个比较研究,针对烃的苄基与二/三元环烷基部分,通过
硫族元素源(特别是
硫和
硒)来实现键的
硫化与
硒化。此外,这一方法揭示了使用
2-巯基苯并噻唑(
MBT)底物时,sp3 C-S偶联产物相较于sp3 C-N偶联产物的优势形成。
