A novel method of annulation was realized from ketones through α,β-epoxy sulfoxides with the aid of endo-type intramolecular radical cyclization. In these reactions 1-chloroalkyl phenyl sulfoxides having phenylseleno group on an end of the alkyl group acted as synthons of the annulation.

A set of zeolite synthesis experiments is described where lattice substitution is varied in the context of the structure of particular structure-directing organocations (at times referred to as templates). In this particular series, the organocations are constructed as members of a fused bicyclo organonitrogen class of compounds, described as having ring construction [l.m.n], where n = 0. We show that
描述了一组沸石合成实验,其中晶格取代在特定结构导向有机阳离子(有时称为模板)的结构背景下发生变化。在这个特定系列中,有机阳离子被构建为稠合双环有机氮类化合物的成员,描述为具有环结构 [lmn],其中 n = 0。我们表明这些化合物可以最好地从转化的起始环酮中获得通过贝克曼重排反应生成亚胺。贝克曼反应的一种特殊方法在我们手中效果最好。在某些情况下,制备和分离异构有机阳离子。通常它们在沸石合成中的使用会产生不同的产品。客体有机阳离子的空间填充细节与合成中开发的晶格类型具有高度相关性。在涉及十氢喹啉衍生物异构体的一个实例中,发现了一种新的沸石 SSZ-48,它仅包含一种异构体。异构体的表征及其在沸石中的用途之后是 (13) C MAS NMR 分析。给出了新沸石的一些细节,并表明在与 SSZ-48(一种 12 环沸石)相似的条件下,可以产生预测 14 环沸石的合理对称操作。异构体的表征及其在沸石中的用途之后是
