m cation are described. The cation is shown to react rapidly in aqueous solution with a wide variety of nucleophiles, yielding o-hydroxy-N-ethylbenzimido derivatives. With carboxylate, cyanate, or thiocyanate anions, or with thiourea, internal rearrangements occur, converting the imido adducts to O-substituted products. The reactions of N-alkylated benzisoxazoles generate a broad spectrum of unusual
描述了N-乙基苯并恶唑鎓阳离子的制备和性质。阳离子在水溶液中与多种亲核试剂迅速反应,生成邻羟基-N-乙基苯甲酰胺基衍生物。与羧酸根,氰酸根或硫氰酸根阴离子,或与硫脲发生内部重排,将酰亚胺加成物转化为O取代的产物。N-烷基化的苯并异恶唑的反应产生了多种不同寻常的物质,这些物质很难通过其他途径获得,并且可以用作合成许多迄今难以接近的系统的起始原料。
