Heterogeneous copper-catalyzed CS coupling via insertion of sulfur dioxide: A novel and regioselective approach for the synthesis of sulfur-containing compounds

A novel and regioselective protocol for CS coupling of naphthylamines via the insertion of sulfur dioxide was developed by employing a heterogeneous copper catalyst, providing desired products in moderate to good yields. This strategy gives a powerful tool for the efficient preparation of sulfur-con...

Description
Summary:A novel and regioselective protocol for CS coupling of naphthylamines via the insertion of sulfur dioxide was developed by employing a heterogeneous copper catalyst, providing desired products in moderate to good yields. This strategy gives a powerful tool for the efficient preparation of sulfur-containing compounds. Control experiments declared that a single-electron transfer mechanism (SET) is responsible for this CS cross coupling reaction. [Display omitted] •High regioselectivity•Heterogeneous copper catalyst can be reused.•The formation of CS bond via insertion of sulfur dioxide.
