      Rh(I)-cod complexes based on P-NH backbone were easily synthesized and they catalyzed the reduction of acetophenone derivatives. Specifically, [Rh(cod)(PPh2NH-C6H4-4-CH(CH3)2)Cl] catalytic system demonstrate good catalytic activity. Additionally, rhodium(I) complex/n-Si heterojunctions have showed excellent rectifying properties at room temperature.

      Catalytically amount of the basic metal-organic framework (IRMOF-3) nanoreactor with organic substrates was found to be an efficient, selective and waste-free green approach for the unsymmetrical Hantzsch coupling reaction. The catalyst can be isolated from the reaction mixture and reused at least 4 times.

    3. Effect of coordination sphere of the copper center and Cu―Cu distance on catechol oxidase and nuclease activities of the copper complexes

      Bin Zheng, Hui Liu, Jie Feng and Jingyan Zhang

      Article first published online: 3 APR 2014 | DOI: 10.1002/aoc.3138

      Dinuclear and polynuclear copper complexes were synthesized and all of them exhibit catechol oxidase and nuclease activity. The catechol oxidase activity of complexes 1–6 is low suggesting that the catechol oxidase activity was affected by the coordination environment of the copper center, when Cu-Cu distance is large. Nuclease activity of binuclear complexes is much higher than that of polynuclear complexes, indicating that the planar ligand structure is more critical than the copper coordination sphere and the Cu-Cu distance.

    4. Pd-catalyzed desulfitative Hiyama coupling with sulfonyl chlorides

      Wei Zhang, Fang Liu, Ke Li and Baoli Zhao

      Article first published online: 1 APR 2014 | DOI: 10.1002/aoc.3139

      Palladium-catalyzed desulfitative Hiyama cross-coupling reactions of various arylsulfonyl chlorides with aryltriethoxysilane have been achieved in good yields. The reported cross-coupling reactions are tolerant to the common functional groups regardless of electron-withdrawing or electron donating, making these transformations as attractive alternatives to the traditional cross-coupling approaches.

    5. Methoxycarbonylation of olefins catalyzed by palladium(II) complexes containing naphthyl(diphenyl)phosphine ligands

      Santiago Zolezzi, Sergio A. Moya, Gonzalo Valdebenito, Gabriel Abarca, Jose Parada and Pedro Aguirre

      Article first published online: 1 APR 2014 | DOI: 10.1002/aoc.3137

      Palladium(II) complexes containing naphthyl(diphenyl)phosphine are precursors of active and selective catalysts in the methoxycarbonylation reaction of several olefins. The best result of olefins used as substrates was obtained with styrene in only 6 hours of reaction with high selectivity towards the branched product.

    6. Pd(l-proline)2 complex: an efficient catalyst for Suzuki–Miyaura coupling reaction in neat water

      Guofu Zhang, Yuxin Luan, Xingwang Han, Yong Wang, Xin Wen and Chengrong Ding

      Article first published online: 1 APR 2014 | DOI: 10.1002/aoc.3129

      Pd(L-proline)2 was successfully used as an efficient catalyst for Suzuki-Miyaura coupling reaction in neat water. Under the optimized conditions, various biaryl compounds were obtained in good to excellent yields and a wide range of functional groups on the tested substrates were well tolerated.

    7. Nickel(II) complex containing N-(4,5-dihydrooxazol-2-yl)benzamide ligands: highly efficient catalyst for Heck coupling reactions

      Junke Wang, Yingxiao Zong, Shenglong Wei and Yi Pan

      Article first published online: 30 MAR 2014 | DOI: 10.1002/aoc.3134

      Thumbnail image of graphical abstract

      Heck reaction catalyzed by Ni(II) containing N-(4,5-dihydrooxazol-2-yl) benzamide has been developed; the coupling of alkenes with aryl iodide or aryl bromide in the presence of potassium carbonate in DMF provides the corresponding products with moderate to good yields. This method possesses obvious advantages such as low-cost catalyst and simple experimental operation.

    8. Ligandless heterogeneous palladium: an efficient and recyclable catalyst for Suzuki-type cross-coupling reaction

      Manoj Mondal and Utpal Bora

      Article first published online: 27 MAR 2014 | DOI: 10.1002/aoc.3135

      A convenient protocol has been developed for the synthesis of unsymmetrical biaryl ketones based on the Pd/C catalyzed Suzuki type cross-coupling reaction in aqueous media.

    9. Carbon–carbon coupling reactions catalyzed by supported Pd porphyrins

      Omid Bagheri, Faranak Sadegh, Majid Moghadam, Shahram Tangestaninejad, Valiollah Mirkhani, Iraj Mohammadpoor-Baltork and Mahsa Safiri

      Article first published online: 19 MAR 2014 | DOI: 10.1002/aoc.3131

      The tetrakis(4-N-methylpyridinium)porphyrinatopalladium(II) iodide supported on Dowex 50WX8 and Amberlite IRA-120 ion-exchange resins was used as heterogeneous, recyclable and active catalysts for the Suzuki-Miyaura and Heck cross-coupling reactions. The catalysts could be recovered and reused several times without significant loss of their catalytic activity.

    10. Investigation of fungicidal activity of 3-piperazine-bis(benzoxaborole) and its boronic acid analogue

      Dorota Wieczorek, Jacek Lipok, Krzysztof M. Borys, Agnieszka Adamczyk-Woźniak and Andrzej Sporzyński

      Article first published online: 13 MAR 2014 | DOI: 10.1002/aoc.3132

      Thumbnail image of graphical abstract

      3-Piperazine-bis(benzoxaborole) and its bis(phenylboronic acid) analogue were investigated in terms of their fungicidal activity against five filamentous fungi: Aspergillus terreus, Fusarium dimerum, Fusarium solani, Penicillium ochrochloron and Aspergillus niger.

      3-Piperazine-bis(benzoxaborole) revealed higher inhibitory activity towards the examined strains than standard antibiotic – amphotericin B, while bis(phenylboronic acid) proved to be inactive. The study unequivocally showed that the presence of the heterocyclic benzoxaborole system is essential for antifungal action of the examined compounds.

    11. Synthesis, characterization and catalytic activity of Pd(II) complexes with N-allyl functionalized imidazol-2-ylidenes in Suzuki–Miyaura reaction

      Rukiye Gümüşada, Namık Özdemir, M. Emin Günay, Muharrem Dinçer, Mustafa Serkan Soylu and Bekir Çetinkaya

      A series of Pd-N-heterocyclic carbene (Pd-NHC) complexes were synthesized and characterized by elemental analysis and spectroscopic methods. In addition, the molecular structures of 3c and 4c were determined by X-ray diffraction studies. These complexes were tested in the Suzuki-Miyaura reactions of phenylboronic acid with aryl bromides.

      Dioxomolybdenum(VI) complex covalently attached on amino-modified graphene oxide (NH2-GO) have been synthesized by a stepwise procedure and the prepared material was used as heterogeneous catalyst for the epoxidation of various alkenes. Furthermore, the catalyst was active and selective for the epoxidation of various alkenes and showed good recoverability without significant loss in activity and selectivity within successive runs.
