Palladium-catalyzed carbonylative cross coupling reaction of organofluorosilanes with organic halides was achieved in the presence of fluoride ion and an atmospheric pressure of carbon monoxide. Alkenyl- or arylfluorosilanes effectively underwent this reaction with alkenyl or aryl iodides in moderate to good yields. Thus, highly functionalized ketones are readily available without protection of reactive
在氟离子和一氧化碳的大气压下,实现了有机氟硅烷与有机卤化物的钯催化羰基交叉偶联反应。烯基-或芳基氟硅烷与烯基或芳基碘化物有效地进行该反应,产率中等至良好。因此,在不保护反应性官能团例如醛,酮,酯,腈和醇的情况下,容易获得高度官能化的酮。为了顺利生成酮,必须使用有机氟硅烷。与芳基碘化物反应后,四芳基硅烷(如芳基(三甲基)硅烷)代替芳酰氟。
