      The syntheses and characterizations of a novel aminophosphine ligand and their Ruthenium(II), Rhodium(I) and Iridium(III) complexes were described. These complexes were used in the transfer hydrogenation of ketones.

    2. 1,3-Dichloro-tetra-n-butyl-distannoxane: a new application for catalyzing the direct substitution of 9H-xanthen-9-ol at room temperature (pages 9–15)

      Ling-yan Liu, Yan Zhang, Kai-meng Huang, Wei-xing Chang and Jing Li

      Article first published online: 26 JAN 2012 | DOI: 10.1002/aoc.1856

      1,3-Dichloro-tetra-n-butyl-distannoxane was firstly used to catalyze the direct substitutions of 9H-xanthen-9-ol with indoles at room temperature to afford a class of 3-(9H-xanthen-9-yl)-1H-indole derivatives in good to excellent isolating yields. Moreover, other nucleophiles (such as diketone and pyrrole) could also smoothly proceed in this methodology.

    3. A PdCl2–ionic liquid brush assembly: an efficient and reusable catalyst for Mizoroki–Heck reaction in neat water (pages 16–20)

      Xianying Shi, Xiaoyan Han, Wenjuan Ma, Juan Fan and Junfa Wei

      Article first published online: 20 DEC 2011 | DOI: 10.1002/aoc.1857

      A highly efficient, environmentally benign and reusable heterogeneous catalytic assembly of PdCl2 held in an ionic liquid brush has been developed for the Heck reactions in neat water without the need for phase transfer catalyst and protection from air. The catalyst can be reused at least eight times without noticeable loss of the catalytic activity.

    4. A new methodology for the oxidation of sulfides with Fe(III) catalysts (pages 21–26)

      Debashis Chakraborty, Payal Malik and Vinod Kumar Goda

      Article first published online: 26 JAN 2012 | DOI: 10.1002/aoc.1859

      A variety of sulfides were converted to the corresponding sulfoxide derivatives with 70% t-BuOOH (water) as the oxidant in the presence of catalytic quantity of Fe2(SO4)3 and salen.

    5. An efficient Stille cross-coupling reaction catalyzed by ortho-palladated complex of tribenzylamine under microwave irradiation (pages 27–31)

      Abdol R. Hajipour, Kazem Karami and Fatemeh Rafiee

      Article first published online: 20 DEC 2011 | DOI: 10.1002/aoc.1860

      The catalytic activity of [Pd{C6H4(CH2N(CH2Ph)2)}(m-Br)]2 complex as an efficient catalyst investigated in the Stille cross-coupling reaction of various aryl halides with phenyltributyltins under microwave irradiation. The substituted biaryls were produced in excellent yield in short reaction times using a catalytic amount of this complex in DMF at 100 °C.

    6. Preparation and properties of flexible free-standing films via polyalkoxysiloxanes by acid-catalyzed controlled hydrolytic polycondensation of tetraethoxysilane and tetramethoxysilane (pages 32–36)

      Takahiro Gunji, Yuki Hayashi, Akemi Komatsubara, Koji Arimitsu and Yoshimoto Abe

      Article first published online: 5 JAN 2012 | DOI: 10.1002/aoc.1861

      Acid-catalyzed controlled hydrolytic polycondensation of tetraethoxysilane and tetramethoxysilane provided polyalkoxysiloxanes PEOS and PMOS, respectively. Flexible and transparent free-standing films were prepared by heating polyalkoxysilanes at 80 °C for one to several days.

    7. Selective aerobic oxidation of alcohols catalyzed by iron chloride hexahydrate/TEMPO in the presence of silica gel (pages 37–43)

      Lianyue Wang, Jun Li, Ying Lv, Gongda Zhao and Shuang Gao

      Article first published online: 5 JAN 2012 | DOI: 10.1002/aoc.1862

      An efficient FeCl3·6H2O/TEMPO catalyst system for alcohol oxidation in the presence of silica gel using molecular oxygen or air as terminal oxidant has been developed. The UV/Vis spectra analysis showed that the Fe (III)-TEMPO complex could serve as the active intermediate species. A plausible mechanism of the catalytic system is proposed.

    8. Encapsulation of manganese(III) complex in NaY nanoporosity for heterogeneous catalysis (pages 44–49)

      Iwona Kuźniarska-Biernacka, Otilia Rodrigues, Maria A. Carvalho, Isabel C. Neves and António M. Fonseca

      Article first published online: 20 DEC 2011 | DOI: 10.1002/aoc.1865

      The encapsulation of Mn(salen) complex was achieved by two different methodologies namely flexible ligand method and complex synthesis in situ. The characterization methods applied confirmed the purity of neat complex and encapsulation of complex. All catalysts are active in oxidation of styrene with tert-butyl hydroperoxide as an oxygen source.
