Reaction of cobaloxime (I) , (CoI)−, with 2-hydroxy- (1a and 1b) and 2-alkoxycyclohexyl halides (1c–1h) gave 2-hydroxy- and 2-alkoxycyclohexyl cobaloximes (III) (2 and 3) . Stereochemistry of the organocobaloxime was independent of the configuration of the starting halides. 2-Allyloxycyclohexyl halides (6a and 6b) gave the organocobaloxime having 9-methyl-7-oxabicyclo[4,3,0]nonane moiety. These results
钴肟 (I) , (CoI)- 与 2-羟基-(1a 和 1b)和 2-烷氧基环己基卤化物(1c-1h)反应得到 2-羟基-和 2-烷氧基环己基钴肟(III)(2 和 3) . 有机钴肟的立体化学与起始卤化物的构型无关。2-烯丙氧基环己基卤化物(6a和6b)得到具有9-甲基-7-氧杂双环[4,3,0]壬烷部分的有机钴肟。这些结果显示了通过电子从钴肟 (I) 转移到卤化物而形成的自由基中间体。
