[摘要]：Recent and ongoing efforts by the Tovar research group to exploit organic halogenation chemistry for the development of complex organic electronic materials are described. Standard synthetic approaches involving free-radical and electrophilic reaction pathways are presented along with strategies that use ionizable protons or triazenes as masking groups for aromatic halides. Forward synthetic processes that highlight the extended chemistry that can be applied to these halogenated substrates to give complex pi-conjugated molecules are also discussed. The examples presented are specific to work from the group's laboratories, but the halogenation procedures are sufficiently general to be suitable for use on many other conjugated frameworks. |
