Visible light promoted sulfonylation and sulfonylcarbonylation reactions of readily available alkenes with TosMIC for the synthesis of valuable vinyl sulfones and β-keto sulfones were described. A reasonable radical involved mechanism is proposed.

In this work, we have described an alternative alkenylation approach to illustrate the metal-like behaviour of iodine in cross-coupling reactions. Alkenylation could proceed through iodide catalysed radical initiation, radical addition and iodine promoted

An improved one-pot method to synthesize vinyl sulfones from unsaturated systems by using molecular iodine/sodium arenesulfinate/sodium acetate as reagents was described. Vinyl sulfones derived from styrene derivatives were generally obtained in good to excellent yields except for those bearing strong electron releasing substituent. Aliphatic alkenes and activated alkenes gave the corresponding vinyl sulfone products in moderate to good yields. Arylacetylenes yielded the respective β-iodovinyl sulfones in good yields while low yield was observed with aliphatic terminal alkyne. The potentials of the method entail simplicity, short reaction time, non-anhydrous reaction conditions, employing inexpensive, non-metallic reagent and integrating two reactions that are commonly accomplished separately into a single operation.

(Diacetoxyiodo)benzene [PhI(OAc)2, DIB] was able to promote the reaction of sodium aryl sulfinate and potassiumiodide (KI) with alkenes and alkynes to afford the corresponding vinyl sulfones and β-iodovinyl sulfones, respectively, in good yield
The effects of the carbonyl group in the cyclization of 1-hexenyl radicals
Serra,Da Silva Correa,Do Vale
, p. 9463 - 9488 (2007/10/02)
The radical chain cyclization of allyl ether derivatives promoted by tosyl halides and light is suppressed by the presence of one carbonyl group conjugated with the double bond (acrylic double bond).
