of aryl fluorides with aryl TBDMS ethers under microwave conditions gave moderate to high yields of the desired products at low catalyst loadings and in short times. In this methodology, electron deficient aryl fluorides possessing substituents, such as nitro, cyano, and ester, were coupled with sterically demanding aryl TBDMS ethers as well as with aryl TBDMS ethers bearing a variety of functionalities
用标题的原氮杂磷杂环戊烷作为促进剂,在微波条件下芳基氟化物与芳基TBDMS醚的偶联在低催化剂负载量和短时间内得到中等至高产率的所需产物。在这种方法中,将具有取代基(例如硝基,氰基和酯)的缺电子的芳基氟化物与空间需求的芳基TBDMS醚以及带有各种官能团(例如甲氧基,卤素和氰基)的芳基TBDMS醚偶联。
