  在不使用外部一氧化碳的情况下，采用芳烃型的炔烃的钯催化加氢酯化反应

  摘要：

  已经开发了在不使用外部一氧化碳的情况下并且在环境压力下使用芳基甲酸酯的炔烃的高效加氢酯化。在钯-黄磷催化剂体系存在下的反应以良好至高收率选择性地提供α，β-不饱和酯。甲酸芳基酯的使用至关重要，烷基甲酸酯根本不反应。降冰片烯和末端烯烃的加氢酯化也容易在相似的反应条件下进行。机理研究表明，加氢酯化过程中发生了芳基甲酸酯向一氧化碳和苯酚衍生物的转化。Xantphos作为芳基甲酸酯的转化和加氢酯化反应的配体都是非常有效的。

  Disclosed is an organic-inorganic hybrid composition. The organic-inorganic hybrid composition includes a curable resin and inorganic particles dispersed in the curable resin. The inorganic particle has a core-shell structure composed of a core containing titanium and barium, and a shell containing at least one selected from zirconium, aluminum and chromium. According to this organic-inorganic hybrid composition, a liquid-phase refractive index of the composition can be improved, and as a result, luminance and light transmittance can be improved in an optical member using the same.
