EF／TEBA存在下六甲基二硅胺烷和芳香醛的反应及其产物三芳基缩二胺的氧化反应

KF/TEBA preasented reaction of aromatic aldehydes with hexamethyldisilazane and oxidation of its products

六甲基二硅胺烷（ＨＭＤＳ）在ＫＦ／苄基三乙基氯化铵（ＴＥＢＡ）体系中．与不同的芳香醛反应均可以获得三芳基缩二胺．后者经高猛酸钾、Ｎ－澳代丁二酰亚胺（ＮＢＳ）或者２，３－二氯－５，６－二氰基对苯醌（ＤＤＱ）氧化，都能得到三芳基取代均三嗪化合物．本文还对反应机理进行了探讨．

In the KF/TEBA system,all reactions of different aromatic aldehydes with hexamethyldisilazane (HMDS) will result in formation of N, N'-diaryl- methylenearylmethane diamines, and all these products will turn to s-triazines through oxidation with KMnO4, NBS or DDQ. The mechanism of the reaction has been discussed.
