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.

In the presence of I2, a simple method for the preparation of arylselanyl anilines from anilines and diselenides is developed. This metal-free iodine-promoted procedure proceeds efficiently under mild reaction conditions, providing a series of

In this report, the highly efficient Rose Bengal-catalysed C(sp2)-H selenylation of indoles, imidazoles and arenes was achieved using a half molar equiv. of diorganoyl diselenides. This metal-free, photo-induced protocol resulted in selenylated

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.
