A new method for the preparation of biaryls via intramolecular 1,5 aryl migration reaction from silicon in silyl ethers to aryl radicals is presented. Various readily available diphenylsilyl ethers can be used as substrates in this reaction. Functionalized aryl groups can also be transferred. The analogous 1,4 aryl migration reaction is less efficient.
提出了一种通过分子内1,5芳基迁移反应从甲硅烷基醚中的硅到芳基的反应制备联芳基的新方法。各种容易获得的二苯基甲硅烷基醚可用作该反应的底物。官能化的芳基也可以被转移。类似的1,4-芳基迁移反应效率较低。
