functionalization of the C(sp3)–H bond of alkanes under metal-free conditions was developed. Using tBuOOtBu as the oxidant, the reaction of disulfides or diselenides with alkanes gave sulfides or selenides in moderate to good yields. The method was very simple and atom-economical.
通过在无金属条件下对烷烃的C(sp 3)-H键进行直接官能化,开发了一种C-S和C-Se键形成的新方案。使用t BuOO t Bu作为氧化剂,二硫化物或二硒化物与烷烃的反应以中等至良好的收率得到硫化物或硒化物。该方法非常简单且原子经济。

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.

The 77Se, 13C and 1H NMR spectra of 46 mostly new compounds with phenylselenenyl groups attached to carbocycles and of three new corresponding selenoxides and the 125Te NMR of phenyltellurenylcyclohexane are reported. Substituent effects on the chemical shifts of these nuclei are compiled and discussed in terms of the configuration and conformation. Low-temperature NMR spectra of some cyclohexane derivatives allowed the evaluation of thermodynamic data, such as A values of the PhSe, PhSe(O) and PhTe groups.
