of NaNO2/HCl was trapped by alkyl aryl radical to form oximes in the E configuration form. The presence of tin/tin chloride mixture in the reaction of the aryl diazonium salts with methyl vinyl ketone produced Michael products along with β-aryl methyl ketones. The predicted α-aryl methyl ketones from the reaction of isopropenyl acetate with the diazotized anilines were obtained using iron or tin/tin
摘要 开发了使用铁粉或锡/氯化锡混合物进行Meerwein芳基化反应的简单快速路线。在铁粉存在下,不同的芳基重氮盐与甲基乙烯基酮、丙烯酸酯和乙酸异丙烯酯反应。在甲基乙烯基酮的情况下,肟的生产被检测为丙烯酸酯的主要产物或与β-芳基甲基酮的混合物。由过量的 NaNO2/HCl 原位生成的 HNO2 被烷基芳基捕获,形成 E 构型形式的肟。在芳基重氮盐与甲基乙烯基酮的反应中锡/氯化锡混合物的存在产生迈克尔产物以及β-芳基甲基酮。使用铁或锡/锡氯化物混合物从乙酸异丙烯酯与重氮化苯胺的反应中获得预测的α-芳基甲基酮。图形概要
