Abstract

(4-Acetamidobenzy1)-and (4-(dimethylamino) benzyl) cobaloximes react rapidly with low concentrations of chlorine and bromine in acetic acid or chloroform at rcam temperature under nitrogen. Both ring-halogenated organometallic products and direct Cc-C cleavage products are formed. However,(4-methoxybenzyl) cobaloxime forms 4-methoxy-2- halotoluene as the exclusive product.(3-Methylbenzyl) cobaloxime undergoes a ...
