Copper-Catalyzed Three Component Regio- and Stereospecific Selenosulfonation of Alkynes: Synthesis of (E)-β-Selenovinyl Sulfones
Liu, Yang,Zheng, Guangfan,Zhang, Qian,Li, Yan
, p. 2269 - 2275 (2017)
A copper-catalyzed highly regio- and stereospecific selenosulfonation of alkynes with arylsulfonohydrazides and diphenyl diselenide has been developed. This novel three component reaction proceeds under very mild conditions and with a broad scope of substrates, providing a wide range of (E)-β-selenovinyl sulfones in good to excellent yields.

A novel and practical method for the selenosulfonation of alkynes with the insertion of sulfur dioxide has been developed. A series of β-(seleno)vinyl sulfones with high levels of regio- and stereoselectivity have been prepared. The key features of this reaction include a broad substrate scope, excellent functional-group tolerance, and amenability to scale-up synthesis. A plausible radical mechanism is proposed to illustrate this reaction.

A novel method for the preparation of β-keto-sulfones through the use of organoselenium reagents in the solid phase by polystyrene-supported benzeneselenosulfonate or tolueneseleno-sulfonate with acetylenes has been developed. Georg Thieme Verlag Stuttgart.
Addition of Phenyl Areneselenosulphonates to Acetylenes: a Route to Acetylenic Sulphones
Miura, Takashi,Kobayashi, Michio
, p. 438 - 439 (2007/10/02)
Treatment of phenyl areneselenosulphonates (1) with terminal acetylenes resulted in the formation of β-(phenylseleno)vinyl sulphones (2), which on treatment with excess of hydrogen peroxide in tetrahydrofuran at room temperature gave acetylenic sulphones
