  脂族烯烃荧光标记的电化学活性交联反应

  摘要：

  尽管交联反应是整合两个或多个功能或特性的宝贵工具，但由于传质困难，电化学合成在交联反应中的应用受到限制。因此，本研究的主要目的是探索由共价键形成引发的电化学交联系统，以构建荧光探针。第二个目的是将探针应用于不溶性靶标。为了实现这些目标，将电化学活性酚衍生物和脂族烯烃结合使用以形成多环化合物。通过[3 + 2]环化反应形成的几种二氢苯并呋喃衍生物表现出荧光。此外，C键形成。

  日期：2008.5.1

  A selective anodic oxidation system in which a carbocation intermediate is generated exclusively by use of a temperature-control led multiphase solution to separate the different stages of the reaction from each other and from the products is described. The formation of a thermomorphic middle layer in an electrolytic solution composed of c-Hex and LPC/MeNO2 results in enhanced interaction between aliphatic alkenes and polar unstable cation.

  The discovery that supporting electrolytes can be effectively confined in typical organic solvents in a c-Hex-based multiphase electrolyte solution has led to the development of a novel heterogeneous continuous flow synthetic system. PTFE fiber functions as a separation filter that can efficiently isolate the c-Hex phase from multiphase electrolyte solutions. This system has demonstrated both electrochemical solvating and carbon-carbon bond forming reactions. Hydrophobic substrates can be introduced into the reactor as c-Hex solutions, which are then electrochemically transformed into the target hydrophobic products that pass through the PTFE fiber as c-Hex solutions.
