  Four kinds of mesoporous material-supported ionic liquid phase catalysts containing chiral Ru complex were synthesized using mesoporous MCM-41, MCM-48, SBA-15 and amorphous SiO2, respectively. The results of N2 sorption and XRD indicated the successful immobilization of chiral Ru complex inside the channels of the mesoporous materials. These immobilized catalysts were evaluated in the asymmetric hydrogenation

  分别使用介孔MCM-41，MCM-48，SBA-15和无定形SiO 2合成了四种含手性Ru配合物的介孔材料负载的离子型液相催化剂。N 2吸附和XRD的结果表明手性Ru配合物成功地固定在介孔材料的通道内。在芳族酮的不对称氢化中评估了这些固定化催化剂，并优化了反应条件。获得了与未固定的对应物相当的催化活性和对映选择性。而且，所有四种催化剂都是稳定的，并且可以容易地回收以重复使用至少四次，而转化率和ee值没有明显降低。尤其是SiO 2基催化剂在第五轮中仍保持高活性和对映选择性。对比实验表明，非均相催化剂中的两种离子液体有利于提高活性物质的稳定性。
• Phosphine-free double carbonylation of iodobenzene in the presence of reusable supported palladium catalysts

  Various silica supported palladium catalysts were prepared and tested in the double carbonylation of iodobenzene in the presence of secondary amines. The catalysts were proved to produce alpha-ketoamide products with excellent selectivity in most cases. At the same time, bulky amines hindered double carbonylation and led to the formation of amides as the main products. Under optimal conditions, the catalysts could be recycled at least six times. An increase in the reaction time led to a decrease in the amount of leached palladium. (c) 2013 Elsevier B.V. All rights reserved.
• Phosphine-free atmospheric carbonylation of aryl iodides with aniline derivatives in the presence of a reusable silica-supported palladium catalyst

  Various palladium catalysts were obtained by the immobilisation of palladium on silica, modified with imidazolium salts. The efficiency of the catalysts was greatly dependent on the choice of the anion of the imidazolium salt, the palladium precursor and on the conditions of heterogenisation. Palladium acetate immobilised on silica with grafted imidazolium chloride moieties was shown to be a selective and recyclable catalyst for atmospheric aminocarbonylation of aryl iodides with aromatic amines in DMF. It was proved that the greater loss of palladium in DMSO can be explained by the formation of soluble palladium complexes. (C) 2014 Elsevier B.V. All rights reserved.

Ionic liquids incorporating Si(OEt)(3) groups have been immobilized on silica in a well-defined manner with the imidazolium moiety remaining intact.
