    1. Dispersion of TiO2 on high-surface-area mesoporous silica: functionalization with tungstophosphoric acid and application in solvent-free, aerobic oxidation of n-hexadecane (pages 1–5)

      Crystalline titanium dioxide (TiO2) nanoparticles of anatase phase were inserted into the high surface area mesoporous silica synthesized using 1-hexadecyl-3-methylimidazolium chloride ionic liquid. Further, the polyoxometalate, 12-tungstophosphoric acid (PW12) was dispersed on the surface of TiO2 to form PW12-TiO2-silica hybrid catalytic materials. The catalytic activity of characterized hybrid material was tested for solvent-free, aerobic oxidation of n-hexadecane and gave the highest conversion of n-hexadecane (21 %) with 45.5 % ketone selectivity.

    2. Aqueous phase transfer hydrogenation of aryl ketones catalysed by achiral ruthenium(II) and rhodium(III) complexes and their papain conjugates (pages 6–12)

      Several ruthenium and rhodium complexes including 2,2’-dipyridylamine ligands substituted at the central nitrogen by an alkyl chain terminated by an N-maleimide group together with a new Rh(III) complex of 2,2’-dipyridylamine catalysed the transfer hydrogenation of aryl ketones in neat water with formate as hydrogen donor. Site-specific covalent anchoring of the N-maleimide complexes to papain endowed this protein with transfer hydrogenase properties towards trifluoroacetophenone. Quantitative conversions and modest enantioselectivities were reached with the Rh-based and the Ru-based metallopapains, respectively.

    3. Synthesis of dendrimers terminated by DABCO ligands and applications of its palladium nanoparticles for catalyzing Suzuki–Miyaura and Mizoroki–Heck couplings (pages 13–18)

      A new kind of silica supported third generation dendrimers capped by 1,4-diaza-bicyclo[2.2.2]octane(DABCO) groups stabilized palladium(0) nanoparticles and their enhanced catalytic activity in Suzuki-Miyaura, and Mizoroki-Heck reactions in excellent yields under mild conditions was reported respectively.

    4. Palladium nanoparticles supported on agarose-catalyzed Heck–Matsuda and Suzuki–Miyaura coupling reactions using aryl diazonium salts (pages 19–22)

      Copper immobilized on amino-functionalized silica is a recyclable, heterogeneous catalyst for the Glaser-Hay alkyne homocoupling. The reaction can be run in air with catalytic amounts of base. The catalyst is active in several solvents and for a wide range of alkynes.

    6. Synthesis and antiproliferative activity of (Z + E)-1-[4-(2-(cyclopentadienyltricarbonylmanganese)-2-oxo-ethoxy)phenyl]-1,2-di(p-hydroxyphenyl)-but-1-ene against breast cancer cells (pages 28–35)

      We describe the synthesis of (Z + E)-1-[4-(2-(cyclopentadienyltricarbonylmanganese)-2-oxo-ethoxy)phenyl]-1,2-di(p-hydroxyphenyl)-but-1-ene. This manganese compound is active against hormone-dependent MCF-7 and hormone-independent MDA-MB-231 breast cancer cell lines.

    7. Synthesis, spectral characterization and biological studies of transition metal(II) complexes with triazole Schiff bases (pages 36–44)

      Triazole derived Schiff base ligands and their Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized and characterized. In vitro antibacterial and antifungal studies of all the compounds against two Gram(+), four Gram(−) and six fungal strains is reported. The activity data showed the metal(II) complexes to be more antibacterial and antifungal than the parent Schiff bases.

      New polymeric triorganotin(IV) urocanic acid derivatives were synthesized and fully characterized.

      The studies showed that although five coordinated and polymeric in the solid-state, the tin compounds are four coordinated and monomeric in solution. In vitro cytotoxic studies show a high cytotoxic activity in human cell lines.
