Reactions of 2,4,6-tri-t-butylnitrosobenzene (1) with alkylmagnesium halides afforded 6-alkyl-1-hydroxy-imino-2,4,6-tri-t-butyl-2,4-cyclohexadienes (2), 4-alkyl-1-hydroxyimino-2,4,6-tri-t-butyl-2,5-cyclohexadienes (3), and N-alkyl-2,4,6-tri-t-butylanilines (4) depending on the Grignard reagents used. The distribution of the reaction products indicated that the oximes were formed via an attack of the
2,4,6-三叔丁基亚硝基苯 (1) 与烷基镁卤化物反应得到 6-烷基-1-羟基-亚氨基-2,4,6-三叔丁基-2,4-环己二烯 (2) 、4-烷基-1-羟基亚氨基-2,4,6-三-叔丁基-2,5-环己二烯 (3) 和 N-烷基-2,4,6-三-叔丁基苯胺 (4) 取决于关于所使用的格氏试剂。反应产物的分布表明,肟是通过阴离子物质分别对邻位和对位碳原子攻击亚硝基而形成的,而 N-烷基苯胺则通过涉及电子的自由基机制形成。从格氏试剂转移到 1。在叔丁基氯化镁的情况下,通过将叔丁基自由基捕获为 1-t-butoxyimino-2,4,4,6-tetra-t-butyl-证实了自由基机制2,5-环己二烯 (8)。
