catalytic amount of CsF in DMF in good yields. The palladium-catalyzed carbonylative cross-coupling reaction of 2 with aryl iodides bearing various functional groups smoothly proceeded giving the corresponding aryl 1-fluorovinyl ketones in good yields under an atmospheric pressure of carbon monoxide. A similar carbonylative cross-coupling reaction of 2 with aryl triflates was also accomplished in the presence
我们发现三丁基(1-氟乙烯基)锡烷(2)可以很容易地由(1-氟乙烯基)甲基二苯基硅烷1(1)和双(三丁基锡)氧化物在DMF中催化量的CsF存在下反应制备产量。钯催化的 2 与带有各种官能团的芳基碘化物的羰基化交叉偶联反应顺利进行,在一氧化碳的大气压下以良好的产率得到相应的芳基 1-氟乙烯基酮。2 与芳基三氟甲磺酸酯的类似羰基化交叉偶联反应也在四丁基碘化铵 (Bu4NI) 作为添加剂的存在下完成。
