Abstract

A series of thiaheterocycles were produced by the reaction of diethyl 2,3‐dibromomaleate or diethyl 2,3‐dibromofumarate with different sulfides without any catalyst. The major products shifted in different conditions. Water was found playing a key role in the generation of carbon–carbon single bonds. Meanwhile, the addition of sulfur could accelerate the reaction and greatly improve the yield of certain products. In addition, unusual, broad single peaks were found in ^13^C NMR spectra of some compounds. Β© 2011 Wiley Periodicals, Inc.

## Abstract **Summary:** The effects of cyclodextrins (CDs) on the formation and color changes of polymerized 10,12‐pentacosadiynoic acid (PCDA) vesicles have been investigated. The strategy used in this study focuses on three different stages in which the CDs can play a role. Among the cyclodextri
