Aspects of the chemistry of 4-tributylstannyl-, 4-trimethylsilyl- and 2- phenylsulfinylallylstannanes
Mortlock, Simon V.,Thomas, Eric J.

The 4-trimethylsilyl- and 4-tributylstannylbut-2- enyl(tributyl)stannanes 3 and 4 have been prepared by treatment of the allylic surfones 6 and 7 with tributyltin hydride under free-radical conditions and shown to react under non-catalysed and Lewis acid
Free radical addition reactions of allylic sulfones to alkenes
Harvey, Iain W.,Phillips, Eifion D.,Whitham, Gordon H.
, p. 6493 - 6508 (2007/10/03)
Intermolecular radical reactions involving formal addition of the sulfonyl and allyl fragments of an allylic sulfone across the double bond of an alkene are described. Reactions are most successful when the allylic sulfone has an electron withdrawing group at the 2-position. Only monosubstituted alkenes give useful yields of adducts, though both electron withdrawing and electron donating substituents are effective.
Radical induced 1,3-rearrangement-cyclisations of some unsaturated allylic sulphones
Smith, Thomas A. K.,Whitham, Gordon H.
, p. 319 - 325 (2007/10/02)
1,3-Rearrangement-cyclisation of unsaturated allylic sulphones, typified by the conversion of the pentenyl substituted allyl sulphone (6) into the cyclic sulphone (8), is described. Reaction is considered to occur by a radical chain mechanism involving addition-elimination of ArSO2*. The scope of the reaction has been explored, using various methyl substituted substrates of type (13) and other structural variants, and found to be quite general.
Mass Spectral Rearrangements of 3-Arylsulphonyl-2-arylthiopropenes and N-(4'-Arylsulphonyl-2'-butynyl)-N-(4"-arylthio-2"-butynyl)anilines
Glaspy, P. E.,Hancock, R. A.,Thyagarajan, B. S.
, p. 281 - 287 (2007/10/02)
Under electron impact the title compounds undergo skeletal rearrangement in the addition to the anticipated modes of cleavage.The 3-arylsulphonyl-2-arylthiopropenes readily eliminate sulphur dioxide.Other modes of fragmentation include rearrangement to a
