Arylseleninic acids were used as an electrophilic selenium source in aromatic substitution reactions, using N,N-substituted anilines and indoles as nucleophiles at 70 °C for 6-15 h. A total of fourteen 4-selanylanilines and five 3-selanylindoles were selectively obtained in good to excellent yields. The starting benzeneseleninic acids are easily prepared from the respective diselenides, are bench stable and easy to handle, affording water as the only waste at the end of the reaction.

A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to access different types of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes through oxidative C-Se/C-S formation via direct C(sp2)-H bond activation was developed. The products were obtained in good to excellent yields using [O or N]-containing arenes, half equiv. of various odorless diorganyl dichalcogenides (S/Se), iodine (20 mol%) as the catalyst and 3 equiv. of DMSO as the oxidant, applying MW irradiation for 10 min.

We describe here an efficient and regioselective synthesis of arylselanyl anilines by copper-catalyzed direct arylselenation of arylamines. Using a catalytic amount of copper iodide in dimethyl sulfoxide at 110 °C under an air atmosphere, a range of aryls
Metal and base-free synthesis of arylselanyl anilines using glycerol as a solvent

We describe here a metal and base-free straightforward method to access arylselanyl anilines using glycerol as a solvent. Starting from N,N-disubstituted anilines and arylselanyl chloride, the protocol is general and was successfully applied to a sort of anilines with different substitution patterns in both the aromatic ring and the nitrogen atom. As desirable for a green synthetic procedure, the non-toxic, low volatile, renewable glycerol was used as a solvent at room temperature. This journal is the Partner Organisations 2014.
