The reactions of arene sulfenyl chlorides, ArSCl, (Ar=Ph, C6Cl5, 2,4 (NO2)2C6H3) with organocobaloximes, RCo(dmgH)2Py, (R=alkyl, benzyl and heteroaromaticmethyl) were carried out under thermal and photochemical conditions. A variety of organic and organometallic products are formed depending upon the substrate cobaloxime. For 3-methoxybenzyl and heteroaromaticmethyl cobaloximes the results suggest
芳烃磺酰氯,ArSCl,(AR = PH,C的反应6氯5,2,4-(NO 2)2 C ^ 6 ħ 3)与organocobaloximes,RCO(dmgH)2 PY,(R =烷基,苄基和heteroaromaticmethyl )在热和光化学条件下进行。取决于底物钴肟,形成各种有机和有机金属产物。对于3-甲氧基苄基和杂芳族甲基钴肟,结果表明它们代表了一类独特的钴肟,其中芳环和CoC键都被芳烃亚磺酰氯攻击而被高度活化。均溶途径和杂合途径均起作用。
