Sulfur Bond

An efficient carbon–sulfur bond formation reaction has been developed under microwave irradiation. This reaction affords a novel and rapid synthesis of thioacetals and sulfides under mild conditions. This method is particularly noteworthy given its experimental simplicity and high generality, and no transition-metal catalysts were needed under our conditions.Key words: microwave, sulfide, thiol, nucleophilic substitution.

Abstract A Cu(II)-catalyzed Csp2-Se and Csp2-Sulfur bond formation was achieved with moderate to good yields without the aid of Lewis acid and base. The reaction is compatible with a wide range of heterocycles such as benzothiazole, thiazole, and imidazole. Also, this typical protocol is found to be active in thio-selenation via S-H activation. Additionally, we proposed a plausible mechanistic pathway involving Cu(III) putative intermediate.
