A novel, efficient, economical strategy for the coupling and direct selenation of arylhydrazines to selenides using SeO2 has been developed. Our method employs SeO2 as the selenium source with hydrazines as coupling reactants to generate selenides via dinitrogen extrusion. This reagent also helped to generate ArSe substitued aniline derivatives via C–H functionalization reaction in good yields. The application of this method in gram scale was also carried out.

The unique oxidizing power of molybdenum pentachloride provides an easy to perform, versatile, and high yielding method to construct carbazoles and the corresponding dibenzo analogues of thiophene, furan, and selenophene. The coupling reaction tolerates a variety of functional groups. The synthesis is highly modular. By this approach a precursor for the naturally occurring carbazole koenigicine was prepared.
