    从 LPdAr(F) 形成 ArF:芳基三氟甲磺酸酯催化转化为芳基氟化物
    摘要:
    容易氟化 氟原子已成为药物中有用的取代基。然而,合成引入它们仍然具有挑战性,因为目前形成碳氟键的方法需要腐蚀性条件或有些奇特的、因此昂贵的试剂。一个症结是传统钯催化剂未能将芳基与配位氟化物偶联。沃森等人。(第 1661 页,8 月 13 日在线发表;参见 Gouverneur 的 Perspective)表明,将钯与精心设计的膦配体配对可使用简单的氟化物盐产生用于芳基氟化的多功能催化剂。该方法可耐受一系列官能团,并应促进多种含氟芳烃目标的有效合成。催化剂能够使用简单的氟化物盐形成多功能的碳氟键。尽管药物重要性日益增加,但氟化芳族有机分子仍然难以合成。目前的方法需要苛刻的反应条件或高度专业化的试剂,使得复杂氟芳烃的制备具有挑战性。因此,开发克服目前使用的这些技术的局限性的通用制备方法是非常有意义的。我们制备了 [LPd(II)Ar(F)] 配合物,其中 L 是联芳单膦配体,Ar 是芳基,并确定了发生还原消除以形成

    One aspect of the invention relates to a metal-catalyzed conversion of aryl halides and sulfonates to the corresponding aryl fluorides. Another aspect of the invention relates to a metal-catalyzed conversion of heteroaryl halides and sulfonates to the corresponding heteroaryl fluorides. Another aspect of the invention relates to a metal-catalyzed conversion of vinyl halides and sulfonates to the corresponding vinyl fluorides. In certain embodiments, simple fluoride sources, such as AgF and CsF, are used. In certain embodiments, the transformations tolerate a wide range of functional groups, allowing for introduction of fluorine atoms into highly functionalized organic molecules.

  • A Fluorinated Ligand Enables Room-Temperature and Regioselective Pd-Catalyzed Fluorination of Aryl Triflates and Bromides

    A new biaryl monophosphine ligand (AlPhos, L1) allows for the room-temperature Pd-catalyzed fluorination of a variety of activated (hetero)aryl trifiates. Furthermore, aryl triflates and bromides that are prone to give mixtures of regioisomeric aryl fluorides with Pd-catalysis can now be converted to the desired aryl fluorides with high regioselectivity. Analysis of the solid-state structures of several Pd(II) complexes, as well as density functional theory (DFT) calculations, shed light on the origin of the enhanced reactivity observed with L1.
