(p-Tolylsulfonyl)- and (p-tolylsulfinyl)methyl radicals reacted with electron rich olefins like vinylsilane, enolethers and silylenolethers in the presence of Bu3SnH to give addition products.Cyclization of sulfonylated and sulfinylated radicals proceeded in good yield and high trans stereoselectivity in the case of enolethers.
