The product ratio for alkylation of oxime salts on oxygen to that on nitrogen has been studied by chromatographic separation. In the methylation and benzylation of p, p'-disubstituted benzophenone oxime sodium salts in ethanol, electronwithdrawing groups markedly promote alkylation on oxygen. In the alkylation of benzophenone oxime sodium salt with+ substituted benzyl halides, electron-withdrawing substituents also favor alkylation on ...
