  Microwave-Promoted and Chelation-Controlled Double Arylations of Terminal Olefinic Carbon of Vinyl Ethers

  摘要：

  Herein we report a rapid, palladium-catalyzed terminal diarylation of the chelating olefin N,N-dimethyl(2-ethenyloxy)ethanamine under noninert conditions utilizing controlled microwave heating as a convenient energy source. Among the aryl bromides examined, both electron-rich and electron-poor substrates were demonstrated to furnish useful yields after only 10-120 min of directed microwave heating at 160-200 degreesC. The good terminal regioselectivity suggests that the precatalyst (Herrmann's palladacycle) serves as a source of weakly coordinated palladium(0) in the investigated high-temperature Heck process.

  Organic reactions catalyzed by palladium, except Pd/C, are conducted with heating by microwave energy. The preferred inorganic reactions involved are coupling reactions in which a new carbon-carbon bond is formed. Preferred reactions are the Heck, Stille and Suzuki reaction. The method provides high yields in very short reaction times.

  除了Pd/C之外，由钯催化的有机反应是通过微波能量加热进行的。所涉及的优选无机反应是偶联反应，其中形成了新的碳-碳键。优选反应包括Heck反应，Stille反应和Suzuki反应。该方法在非常短的反应时间内提供高收率。
