A palladium catalyzed Negishi-type α-arylation of α-fluoroketones with electron-rich and electron-deficient aryl halides or phenyl triflate has been developed. This direct mono-α-arylation method generate a variety of ternary α-aryl-α-monofluoroketones easily in good to excellent yields using XPhos as ligand and Cs2CO3 as mild base.
已经开发了钯催化的α-氟代酮的Negishi型α-芳基化反应,该反应具有富电子和电子不足的芳基卤化物或三氟甲磺酸苯酯。使用XPhos作为配体和Cs 2 CO 3作为温和的碱,这种直接的单α-芳基化方法可以轻松地以良好或优异的产率生成各种三元α-芳基-α-单氟酮。
