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 selenoxides forming 9-oxoselenoxanthenium and triaryl selenonium hexafluorophosphates via interaction with heptyl phenyl ether and anisole in the MeSO3H-P2O5 mixture followed by treatment with KPF6 have been obtained via selenoxantene-9-one and diphenyl selenide derivatives oxidation with m-chloroperoxybenzoic acid or hydrogen peroxide.

A novel and simple microwave-assisted one-pot protocol to prepare symmetrical diaryl selenides has been developed. A cross-coupling reaction between aryl iodide and elemental selenium takes place in the presence of KOH and a catalytic amount of Cu2O/NH2CH2CH 2NH2, leading to C-Se bond formation. The reactions are highly efficient with a reaction time of 1 h under microwave irradiation and yields from 50% to 90%.
Synthesis and reactivity of dibenzoselenacycloheptynes

Dibenzoselenacycloheptynes were prepared in three steps from commercially available reagents and trapped in situ with benzyl azide to form the corresponding triazoles. Surprisingly, the dibenzoselenacycloheptynes also abstracted hydrogen atoms from solvents such as THF or toluene, forming dibenzoselenacycloheptene products. These alkenyl compounds arise from a hydrogen transfer reaction from solvent to the unisolable intermediate, and we postulate that the reaction proceeds via a radical mechanism originating from the strained alkynyl bond that has unusually high radical character.
