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.
