The compounds p-XC6H4SO2Cl (X = Cl, Br, I, OMe) react regiospecifically with allyl-, 2-methylallyl-, 3-methylallyl- and 3,3-dimethylallyl-cobaloximes under thermal and photochernical conditions. A rearrangedorganic 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
化合物p -XC 6 H 4 SO 2 Cl(X = Cl,Br,I,OMe)在热和光化学条件下与烯丙基-,2-甲基烯丙基-,3-甲基烯丙基-和3,3-二甲基烯丙基-钴肟发生区域特异性反应。 。在每种情况下均获得了重排的有机产物。在光化学反应中产率要好得多。涉及链机理,其中有机磺酰基和钴肟(II)是链增长的物质。当反应在氧气存在下进行时,砜的产率会大大降低。
