Abstract
Five 1,3-disubstituted imidazolium salts were synthesized. Their Heck reaction activities were evaluated. A convenient, efficient and high yielding procedure based on these compounds for the arylation of olefins was developed. Heck reactions mediated by these palladium-N-heterocyclic carbene complexes were conducted under air and even in the presence of several common oxidants.
摘要
合成了五种1,3 - 二取代咪唑鎓盐。评估了它们的Heck反应活性。基于这些化合物开发了一种用于烯烃芳基化的便捷、高效且高产率的方法。由这些钯 - N - 杂环卡宾配合物介导的Heck反应在空气中甚至在几种常见氧化剂存在的情况下进行。
