2-alkylsulfonyl-2‘-biphenyl radicals, in which the alkyl group is primary, secondary, or tertiary, were generated and the products of their reactions investigated. Dibenzothiophene S,S-dioxide was not identified among the products, which arose mainly from intramolecular hydrogenabstraction from the alkyl group or addition to the solvent, benzene. On this basis, it is concluded that homolyticsubstitution at sulfonyl
