A three-component reaction of olefin, diselenide and water, alcohols, phenol, carboxylic acid, or amine by a commercially available hypervalent iodine(III) reagent, PhIO, was developed. This method provides access to a wide range of vicinally functionalized selenoderivatives under ambient conditions with mostly excellent yields and high diastereoselectivity. The developed reaction displays high levels
A visible-light-induced oxidativecoupling of diselenides with readily available vinylarenes is demonstrated. This benign protocol allows one to access a wide range of α-aryl and α-alkyl selenomethyl ketones in good yields with excellent functional group compatibility. The distinct advantages of this protocol over all previous methods include the use of a green solvent and air as an oxidant and the
An intermolecular aminoselenation of alkenes with sulfonimides and diselenides is achieved via a visible-light-induced three component reaction. A broad variety of aminoselenation products is accessible in good yields with excellent functional group compatibility. Additional features of this new protocol include being additive- and photocatalyst-free and the use of natural sunlight as well as suitability

Abstract An improved approach to the synthesis of organic diselenides is reported. The process involves the reaction of organic halides with selenium, carbon monoxide, and water under atmospheric pressure in the presence of an inorganic base, sodium hydroxide, to afford organic diselenides in good yields.
