• A new method of introducing a trifluoromethyl group into an aromatic ring
  作者：Marko Zupan、Zvonko Bregar

  DOI：10.1016/s0040-4039(00)89064-4

  日期：1990.1

  Trifluoromethyl derivatives of aromatic molecules were prepared from aromatic halides, converted to dithiocarboxylic acids through formation of Grignard reagents, followed by fluorination with xenon difluoride at room temperature.

  A novel strategy via thermoregulated phase-transfer catalysis (TRPTC) to separating catalyst in aqueous/organic biphasic system has been successfully established in a copper-mediated activators generated by electron transfer for atom transfer radical polymerization (AGET ATRP) of methyl methacrylate (MMA), using a thermoresponsive PEG-supported dipyridyl ligand (PSDL) as the ligand and an alkyl pseudohalogen

  催化剂配合物可以在反应温度（90°C）下从初始催化剂水溶液转移到有机相中，以催化MMA的均相聚合，然后再从有机相转移到水溶液中，一旦催化剂从聚合溶液中分离出来冷却至室温（25°C），同时在有机层中保留良好控制的产品（PMMA）。另外，聚合可以在有限量的空气存在下进行，这不仅不牺牲聚合的可控性，而且仅通过简单地有效改变温度就可以使催化剂再循环。
