Chalcones made easy: CarbonylativeHeckreactions of aryl and alkenyl triflate derivatives with carbon monoxide and aromatic olefins proceed in the presence of palladium catalysts (see scheme; dppp=1,3‐bis(diphenylphosphino)propane, Tf=triflate; R=aryl, vinyl). With this process, the gap between the Suzuki and Sonogashira carbonylativereactions is finally bridged.
轻松实现Chalcones:在钯催化剂的存在下,芳基和链烯基三氟甲磺酸酯衍生物与一氧化碳和芳族烯烃的羰基Heck反应进行(参见方案; dppp = 1,3-双(二苯基膦基)丙烷,Tf =三氟甲磺酸酯; R =芳基乙烯基塑料)。通过这个过程,Suzuki和Sonogashira羰基化反应之间的差距最终得以弥合。
