The compounds p-XC6H4SO2Cl (X = Cl, Br, I, OMe) react regiospecifically with allyl-, 2-methylallyl-, 3-methylallyl- and 3,3-dimethyl-cobaloximes under thermal and photochemical conditions.A rearranged organic product is obtained in each case.The yields are much better in photochemical reactions.A chain mechanism is involved in which the organosulphonyl radical and cobaloxime(II) are the chain propagating species.Yields of the sulphones are drastically reduced when the reactions are carried out in the presence of oxygen.
