A novel radical substitution reaction is described; the reaction involves the intramolecular addition of carbon-centred radicals to arylsulfoxide and aryl sulfide substituted indoles.
novel radical substitutionreaction of aromatic sulfones is presented. Thus, α-heterocyclic aromatic sulphones derived from indole, pyrrole, pyrazole, furans and thiophenes undergo rapid and high yielding ipso-substitution to furnish organostannanes. This methodology has been extended to β-heterocyclic aromatic sulfones derived from indoline and dibenzofuran. The methodology has some liminations as
