Metal-free synthesis of unsymmetrical selenides from pyridinium salts and diselenides catalysed by visible light

We report the first metal-free selenolations of pyridinium salts with diselenides to prepare unsymmetrical organoselenides catalysed by visible light. This protocol is an efficient and green method for the preparation of unsymmetrical organoselenides because metal-free conditions and readily accessible diselenides are used.

Trichloroisocyanuric Acid-Promoted Synthesis of Arylselenides and Aryltellurides from Diorganyl Dichalcogenides and Arylboronic Acids at Ambient Temperature

A transition-metal-free method for the synthesis of arylselenides and aryltellurides has been established based on the oxidative cross-coupling between diorganyl dichalcogenides and aryl boronic acids. With trichloroisocyanuric acid as an oxidant, the reaction proceeded smoothly to afford the desired products in 45–97% yields at ambient temperature. Three reaction reagents used in this method are stoichiometric and the oxidation by-product isocyanuric acid can be easily isolated and recovered. Besides of arylboronic acids, aryl trifluoroborates and aryl trihydroxyborates salts are also able to perform this transformation. (Figure presented.).

Photocatalyst-free photoredox synthesis of diaryl selenides by reaction of diselenides with aryldiazo sulfones

A photcatalyst-free photoredox synthesis of diaryl selenides has been developed by coupling reaction of diselenides with aryldiazo sulfones. The reaction was accelerated under visible light irradiation without using a photocatalyst or photosensitizer. This approach facilitates the synthesis of diaryl selendes with a wide range of functional group tolerance.

Transition metal-free coupling reactions of benzylic trimethylammonium salts with di(hetero)aryl disulfides and diselenides

A new protocol was developed to synthesize (enantioenriched) thioethers and selenoethers from (chiral) benzylic trimethylammonium salts and di(hetero)aryl disulfides or diselenides. These syntheses were promoted by the presence of weak base and did not require the use of any transition metal, and resulted in the target products with good to excellent yields (72-94%). Using quaternary ammonium salts synthesized from enantiomerically enriched amines led to highly enantiopure benzylic thioethers and selenoethers (94-99% ee) with configurations reversed from those of their enantioenriched quaternary ammonium salts.

Method for preparing asymmetric organic selenium ether compounds through metal-free chemical oxidation method (by machine translation)

The method is mild in reaction condition, convenient to operate, high in 1 reaction condition, convenient 2 to operate, high in safety, wide in substrate range, high 2 - 8h in yield, particularly suitable for reaction of various poor 3 electric and sterically hindered arylboronic acid and diselenoxy ether, and capable of finishing most of the reaction 4h.

Zn in ionic liquid: An efficient reaction media for the synthesis of diorganyl chalcogenides and chalcogenoesters

A straightforward and efficient methodology is described to synthesize structurally diverse diorganyl selenides, sulfides, seleno- and thioesters by using commercially available Zn dust in ionic liquid. Excellent yields were achieved under neutral conditions at room temperature in a short time. The solvent/ionic liquid is reusable and exhibited higher performance as compared with organic solvents.

Synthesis of diorganyl selenides mediated by zinc in ionic liquid

Figure presented A new approach for the synthesis of diorganyl selenides is described. By using economically attractive zinc dust in BMIM-BF4, a series of diorganyl selenides were efficiently achieved in excellent yields, under neutral reaction conditions. Compared to the usual organic solvents, BMIM-BF4 exhibited higher performance with the advantage to be reused up to five successive runs.

Ionic liquid: An efficient and recyclable medium for synthesis of unsymmetrical diorganyl selenides promoted by InI

In an environmentally friendly protocol, InI was used as a reducing agent for the Se-Se bond to prepare unsymmetrical diorganyl selenides with very short reaction times, mild conditions and excellent yields using (bmim)BF4 as a recyclable solvent.

Zinc-mediated cleavage of diselenides: A novel synthesis of unsymmetrical diorganyl selenides in aqueous media

A convenient synthetic method has been developed for the preparation of unsymmetrical selenides through a one-pot zinc-mediated reaction of diselenides and active organic halides in aqueous media.
