Intermediates in the reaction of N,N-dimethylanilines with palladium (II) acetate were trapped by acetate ion or oxygen to give N-methyloxygenated and demethylated products, while the trapping by other anilines gave homo- and cross-coupling cyclodimers. The reactions proceed via radical cation formation induced by the palladium salt.
N,N-二甲基苯胺与
醋酸钯(II)反应的中间产物被
醋酸离子或
氧气捕获,生成 N-甲基氧合和脱甲基产物,而被其他
苯胺捕获则生成同偶联和交叉偶联环二聚体。反应是通过
钯盐诱导的自由基阳离子形成进行的。
