Abstract: The reactions of but-3-enyl cobaloximes with thiophene-2-sulphonyl chloride under thermal and photochemical conditions give the corresponding cyclopropylmethyl sulphones. A similar reaction with cyclopent-2-enylmethyl and cyclohex-2-enylmethyl cobaloximes gives a mixture of cis- and trans- bicyclic products. Cycloalkane, spirocycloprop-2-yl sulphone is formed exclusively from the reaction of 2-(cycloalk-1-enyl)ethyl cobaloxime. The reactions are interpreted in terms of SH 2 mechanism.
