Abstract The reaction of dimethylhydrazones with dimethyl sulfate and potassium carbonate gives the N,N,N-trimethyl methylsulfate (e.g. 3a) primarily which may be hydrolyzed to the ketone subsequently. Tosylhydrazones give the N-methyl derivatives only and not the related ketones. Deviating results by A. Kamal et al. cannot be reproduced.
摘要 二甲基腙与硫酸二甲酯和碳酸钾反应生成N,N,N-三甲基甲基硫酸盐(如3a),随后可水解为酮。甲苯磺酰腙仅产生 N-甲基衍生物,而不产生相关的酮。A. Kamal 等人的偏差结果。无法复制。
