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 of functional group compatibility and is suitable for the late-stage functionalization of styrene-functionalized biomolecules. Preliminary investigations on the mechanism of the reaction are also presented.

, p. 346 - 353 (2013/05/09)
In this article, we have studied the generation of a bissulfinylmethyl radical from the corresponding TEMPO and phenylselenyl bissulfoxide precursors. No univocal formation of the bissulfinylmethyl radical has been observed. Instead, complex mixtures have been obtained in thermal or photochemical conditions, showing prominent C-S homolytic bond cleavage.

A novel role of zeolite NaY in the thermal reaction of alkyl aryl selenoxides in its supercages
Zhang, Wanxuan,Yu, Haitao,Gao, Yu,Meng, Jiben,Matsuura, Teruo
, p. 498 - 499 (2007/10/03)
Thermal reaction of alkyl aryl selenoxides in the presence of water or methanol in the supercage of zeolite NaY gave β-hydroxy- or β-methoxyalkyl aryl selenides, respectively, and NaY played a novel role to stabilize reactive ArSeOH and to separate an anion of -OH from a carbonium ion which was simultaneously present with the -OH in a supercage.
