  摘要：

  研究了以噻吩为中心并通过柔性间隔基连接到刚性侧臂核心单元和末端烷氧基链的分子的中间相组织。已经研究了通过改变间隔子的跨度以及末端链的长度实现的三十个同源物。除了观察到的所有介晶的对映向列相外，间隔基的增加以及末端链的长度也导致了近晶C相。通过依赖温度的X射线衍射测量研究的近晶相分子结构揭示了一种有趣的行为，该行为取决于间隔基的长度相对于末端链的长度。因此，对于间隔物长度较短的分子，观察到了相互交叉的部分双层结构倾斜，而对于间隔长度较长的那些，则观察到倾斜的单层排列。对代表性介晶进行的高分辨率固态（13）C NMR研究表明，所有分子均为U形，表明分子间的相互作用和分子动力学而非分子形状是观察到的行为的原因。已经考虑了中间相组织的模型，并且根据介晶的不相容部分的分离以及导致观察到的层状有序的空间挫败感来理解结果。表明分子间的相互作用和分子动力学而不是分子形状是观察到的行为的原因。已经考虑了中间

  A one-pot procedure for deprotecting carboxylic esters under nonhydrolytic conditions is described. Typical alkyl carboxylates are readily deblocked to the carboxylic acids by the action of aluminum powder and iodine in anhydrous acetonitrile. Cleavage of lactones affords the corresponding ω-iodoalkylcarboxylic acids. Aryl acetylates undergo deacetylation with the participation of the neighboring group

• Correlation of carbon-13 substituent-induced chemical shifts:Meta- andpara-substituted methyl benzoates
  作者：Miloš Buděšńský、Otto Exner

  日期：1989.6

  Carbon‐13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethyl sulphoxide‐d6. The substituent‐induced chemical shifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and for meta derivatives in particular this correlation is both overpara meterized and imprecise. A much better
