• Efficient construction of C–C bonds from aryl halides/aryl esters with arylboronic acids catalysed by palladium(II) thiourea complexes

  Interestingly, the palladium(II) thiourea complexes showed the highest catalytic activity with 0.1 mol% catalyst loading in Suzuki–Miyaura cross‐coupling reactions utilizing a range of aryl bromides/unactivated aryl chlorides with arylboronic acids as coupling partners in aqueous–organic media. Syntheses of diaryl ketones using aryl esters and arylboronic acids as coupling partners were also achieved with low

  已成功地合成了一组新的包含苯基（噻唑基）硫脲配体的钯（II）配合物，并借助分析和光谱（IR，UV-可见光和NMR）方法对其进行了表征。单晶X射线衍射法证实了新钯配合物中硫脲配体的N ^ S配位模式具有N ^ S配位模式的扭曲方平面几何结构。有趣的是，钯（II）硫脲配合物在铃木-宫浦交叉偶联反应中显示出最高的催化活性，催化剂负载量为0.1摩尔％，利用一系列芳基溴化物/未活化的芳基氯化物与芳基硼酸作为水性有机介质中的偶合伙伴。使用芳基酯和芳基硼酸作为偶合伙伴合成二芳基酮也可以在20小时内以较低的催化剂负载量实现。我们的催化剂的潜力通过其广泛的底物范围，低的催化剂负载量和高的分离产率得到了证明。此外，还研究了关键参数如溶剂，碱，温度和催化剂用量的影响。

  aryl and indole boronates has been explored in good to excellent yields. In situ generation of nano-Cu2O from CuCl2 under the reaction conditions has been discovered for the first time. The generality of the reaction was further demonstrated by the arylation of 5-iodopyrimidine, iodopyridines, iodobenzenes, and diiodobenzenes and resulted in good to moderate yields. Moreover, bisindole alkaloid Scalaridine

  已经研究了无配体铜催化3,5-二碘吡啶与芳基和吲哚硼酸酯的Suzuki-Miyaura偶联，收率良好。原位生成的纳米铜的2从氯化亚铜ø 2在反应条件下已经发现首次。通过5-碘嘧啶，碘吡啶，碘苯和二碘苯的芳基化进一步证明了反应的一般性，并产生了良好至中等的收率。此外，双吲哚生物碱Scalaridine A已成功地以60％的总收率合成。
• Control of reactive site in palladium-catalyzed Grignard cross-coupling of arenes containing both bromide and triflate

  Reaction of 4-bromophenyl triflate (1) with phenylmagnesium bromide in the presence of 5 mol % of PdCl2(dppp) gave 97% yield of 4-bromobiphenyl (2a), which was formed by selective replacement of triflate in 1 by phenyl. On the hand, bromide in 1 was substituted with the phenyl Grignard reagent selectively by use of PdCl2(meo-mop)2 to give 4-biphenyl triflate (3a) in high yield. The selective substitution

  4-溴苯基三氟甲磺酸酯（1）与苯基溴化镁在5 mol％的PdCl 2（dppp）存在下反应，可制得97％的4-溴联苯（2a），该产物是通过用苯基选择性取代1中的三氟甲磺酸酯而形成的。另一方面，通过使用PdCl 2（mem-mop）2选择性地用苯基格氏试剂代替溴中的1，从而以高收率得到了三氟甲磺酸4-联苯酯（3a）。在1与钯（0）膦配合物的化学计量反应中，证明了选择性取代发生在氧化加成钯（0）物种上。
