  Synthesis of Functionalizedp-Phenylene Oxide Oligomers

  摘要：

  Oligomers of p-phenylene oxides have been synthesized by coupling of substituted phenols and aryl bromides in the presence of cuprous chloride. The chain length varies from 2 to 5 phenyl rings functionalized at one end by an OH and OMe group and at the other end by an OH, OMe or NO2 functions. The oligomers could be used in material science and as building blocks in supramolecular chemistry. Methods for chemoselective demethylation of methoxy groups were developed.

  日期：——

  Highly selective coupling of diiodoarenes with phenols or phenthiols can be performed by using a low-cost, benign character and readily available Fe/Cu catalytic system in the absence of ligands. It is noteworthy that the desired dimeric aryl ethers or sulfides could be obtained in high yields by coupling between diiodoarenes and phenols, or diphenols with aryl iodides.

  可以使用一种低成本、温和且易得的Fe/Cu催化体系，在无配体的条件下，选择性地将二碘芳烃与酚类或硫酚进行偶联。值得注意的是，通过二碘芳烃与酚类或二酚与芳基碘化物之间的偶联，能够以高产率获得所需的二聚芳醚或硫化物。

• Rhodium(NHC)-Catalyzed <i>O</i>-Arylation of Aryl Bromides
  作者：Hyun Jin Kim、Min Kim、Sukbok Chang

  DOI：10.1021/ol200603c

  日期：2011.5.6

  The first example of the rhodium-catalyzed O-arylation of aryl bromides is reported. While the right combination of rhodium species and N-heterocyclic carbene (NHC) offered an effective catalytic system enabling the arylation to proceed, the choice of NHC was determined to be most important. The developed O-arylation protocol has a wide range of substrate scope, high functional group tolerance, and flexibility allowing a complementary route to either N- or O-arylation depending on the choice of NHC.
