Pd‐catalyzed Suzuki–Miyaura cross‐coupling between (hetero)aryl halides (Cl, Br, I) and versatile, moisture‐stable mono‐ and bifunctional potassium aryltrifluoroborates proceeded efficiently and chemoselectively in air and under generally mild conditions; a catalyst loading as low as 1 mol % combined with Na2CO3 as a base in choline chloride/glycerol (1:2) deep eutectic solvent (DES) was used as a
钯催化的(杂)芳基卤化物(Cl,Br,I)与通用的,湿气稳定的单和双官能芳基三氟硼酸钾之间的钯催化的Suzuki-Miyaura交叉偶联在空气中和一般在温和的条件下有效且化学选择性地进行;与Na 2 CO 3结合的催化剂负载量低至1 mol%作为氯化胆碱/甘油(1:2)中的碱,低共熔溶剂(DES)被用作可持续和对环境负责的介质。催化剂,碱和DES可以轻松且成功地回收多达六次,而E因子低至8.74。提供了有价值的联芳基和三联苯衍生物,产率高达98%。比较和讨论了50多个反应。该方法已用于非甾体抗炎药Felbinac和Diflunisal的合成。

through bridging 3,3′-tpdc and dmf ligands to form a 1D chain. The resulting 1D metal chains are further interconnected by 3,3′-tpdc ligands to form 3D frameworks without porosity. The thermolabile dmf bridging ligands were easily removed by heating at 180 °C under vacuum for 5 h. The activated MOFs I and II exhibited very low gas uptake of N2, CO2, and H2 after removal of the dmf bridging ligands
我们在此报告了两种新的同构三维 (3D) MOF,其通式为 [M(3,3'-tpdc)(dmf)] [M = CoII (I), MnII (II)]金属离子和 C2h 对称双位桥连配体三联苯-3,3'-二羧酸酯 (3,3'-tpdc)。两种同构 MOF 均在单斜空间群 C2/c 中结晶。金属离子由四个 Ocarboxylate (η1:η1:µ2) 和两个 µ2-Odmf 原子以扭曲的八面体几何结构配位。金属中心通过桥接 3,3'-tpdc 和 dmf 配体相互连接,形成一维链。所得的一维金属链通过 3,3'-tpdc 配体进一步互连,形成没有孔隙的 3D 框架。通过在真空下在 180°C 下加热 5 小时,可以轻松去除不耐热的 dmf 桥接配体。活化的 MOFs I 和 II 对 N2、CO2、和去除 dmf 桥连配体后的 H2。还研究了活化的 I 和 II 对碘客体分子的包封。还阐明了碘包封的
