with the formation of 4-(dialkylaminoor piperidino)methylene-3,5-di-tert-butylcyclohexa-2,5-dienones III. The dialkylamine formed in the dehydrochlorination step, as found in additional experiments, further reacts with I to form salt V [3, 4]. When the reaction of I with IIa was performed in diethyl ether, a crystalline mass consisting of IVa and Va was obtained. By its treatment with ethyl diphenylphosphinite
我们发现该键也被 4-羟基-3,5-二叔丁基苯亚甲基氯 I 裂解。 I 与缩醛胺 II 的反应在混合反应物(纯或在溶剂如乙醚或己烷中)时发生放热)。无论缩醛胺结构和反应物比例如何,偕二氯化物 I 都会发生脱氯化氢和脱氯胺化反应,形成 4-(二烷基氨基或哌啶基)亚甲基-3,5-二叔丁基环六-2,5-二酮 III。如在其他实验中发现的,在脱氯化氢步骤中形成的二烷基胺进一步与 I 反应形成盐 V [3, 4]。当 I 与 IIa 在乙醚中进行反应时,得到由 IVa 和 Va 组成的结晶物质。通过用二苯基亚膦酸乙酯处理,我们获得了单独的产品:
