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.

The C–O bond formation represents a fundamental chemical transformation in organic synthesis to develop valuably oxygenated (hetero)arenes. Particularly, the direct and regioselective C–H bond oxygenation of privileged amides, using a transition metal catalyst and a mild oxygenating source, is a step-economy and attractive approach. During the last decade, considerable progress has been realized in the direct C−H oxygenation of primary, secondary and tertiary amides. This Minireview compiles the advances in transition-metal-catalyzed oxygenation of C(sp<sup>2</sup>)−H and C(sp<sup>3</sup>)−H bonds on various amides with diverse oxygenation sources. The review is categorized into two different major sections: (i) C(sp<sup>2</sup>)−H oxygenation and (ii) C(sp<sup>3</sup>)−H oxygenation. Each section is discussed based on the directing group (monodentate and bidentate) attached to the amide derivatives.
