Free radical reaction of sodium arenesulfinates with acetylenes: New regio- and stereoselective preparation of (E)-β-(phenylseleno)vinyl sulfones

Free radical reaction of terminal acetylenes with sodium arenesulfinates and diphenyl diselenide in aqueous acetic acid affo31yrded high yields of the regio- and stereoselective (E)-β-(phenylseleno)vinyl sulfones.

Addition of Phenyl Areneselenosulphonates to Acetylenes: a Route to Acetylenic Sulphones

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
