1,4-Bis(alkylsulfonyl)benzenes 2 exhibit the formation of a fairly stable a
nion radical under cathodic electron transfer. Its fragmentation leads both
to 1-alkylsulfonyl-4-alkyl benzenes (ipso substitution) and 4-alkylsulfony
lphenoxy ions, the presence of the latter suggesting a new mode of cleavage
for strongly activated sulfones. (C) 2000 Published by Elsevier Science Lt
