  钯-镍二元纳米团簇协同催化邻杂环杂环芳基溴化物的Suzuki-Miyaura反应

  摘要：

  据报道，钯-镍二元纳米团簇是邻杂环固定的位阻芳基溴化物的Suzuki-Miyaura交叉偶联的新催化剂体系。使用已报道的Pd / Ni盐/络合物或单个Pd / Ni纳米粒子作为催化剂所获得的较差结果表明，Pd-Ni纳米簇中Pd和Ni纳米粒子具有协同催化作用。关于2-芳基苯并恶唑部分和硼酸的变化的广泛的底物范围提供了多样性产生和催化剂可再循环性的手段，这标志着明显的优势。

• Catalytic constructive deoxygenation of lignin-derived phenols: new C–C bond formation processes from imidazole-sulfonates and ether cleavage reactions

  feedstock for less oxygenated fine chemicals, several catalytic C-C bond forming reactions utilising guaiacol imidazole sulfonate are demonstrated. These include the cross-coupling of a Grignard, a non-toxic cyanide source, a benzoxazole, and nitromethane. A modified Meyers reaction is used to accomplish a second constructive deoxygenation on a benzoxazole functionalised anisole.

  Ni–Pd binary nanoclusters are reported for the activation of the C–O bond for Suzuki–Miyaura cross-coupling of bioactive heterocycle-tethered sterically hindered aryl carbonates with aryl boronic acids. The reaction does not take place in the presence of either the Pd or Ni salts/complexes or the individual Pd or Ni nanoparticles, indicating ensembling cooperativity between the Pd and Ni nanoparticles

  据报道，Ni-Pd二元纳米团簇可激活Suzuki-Miyaura将具有生物活性的杂环束缚的空间受阻芳基碳酸酯与芳基硼酸的C-O键活化。该反应不会在Pd或Ni盐/络合物或单个Pd或Ni纳米粒子的存在下发生，这表明Pd和Ni纳米粒子在激活C-O键上具有协同作用。

  The 2-(2-arylphenyl)benzoxazole moiety has been found to be a new and selective ligand for the enzyme cyclooxygenase-2 (COX-2). The 2-(2-arylphenyl)benzoxazoles 3a-m have been synthesized by Suzuki reaction of 2-(2-bromophenyl)benzoxazole. Further synthetic manipulation of 3f and 3i led to 3o and 3n, respectively. The compounds 3g, 3n, and 3o selectively inhibited COX-2 with selectivity index of 3n much better than that of the COX-2 selective NSAID celecoxib. The in vivo anti-inflammatory potency of 3g and 3n is comparable to that of celecoxib and the nonselective NSAID diclofenac at two different doses, and 30 showed better potency compared to these clinically used NSAIDs.

  The palladium–nickel binary nanocluster is reported as a new catalyst system for Suzuki–Miyaura cross-coupling of ortho-heterocycle-tethered sterically hindered aryl bromides. The inferior results obtained with the reported Pd/Ni salts/complexes or individual Pd/Ni nanoparticles as catalyst reveal the cooperative catalytic effect of the Pd and Ni nanoparticles in the Pd–Ni nanocluster.
