  • Photosensitised regioselective [2+2]-cycloaddition of cinnamates and related alkenes
    作者:Santosh K. Pagire、Asik Hossain、Lukas Traub、Sabine Kerres、Oliver Reiser
    DOI:10.1039/c7cc06710k
    日期:——
    An efficient method for the synthesis of substituted cyclobutanes from cinnamates, chalcones, and styrenes has been developed utilizing a visible-light triplet sensitisation mode. This reaction provides a diverse range of substituted cyclobutanes in high yields under mild conditions without the need of external additives. Good regioselectivity is obtained due to strong π–π-stacking of arene moieties
    利用可见光三重态敏化模式已经开发了一种从肉桂酸酯,查耳酮和苯乙烯合成取代环丁烷的有效方法。该反应在温和条件下无需外部添加剂即可高收率地提供各种范围的取代的环丁烷。良好的区域选择性是由于芳烃部分的强烈π-π堆积而获得的,而非对映选择性则取决于芳烃底物的电子效应或邻位取代。木质素天然产物(±)-丹哥酚的形式合成证明了这种转化的效用。

    serves as an effective promoter for the room-temperature stereoselective synthesis of α,β-unsaturated esters, fluorides, and nitriles from a wide array of aromatic, aliphatic, heterocyclic, and cyclic aldehydes and ketones, using a range of Wadsworth−Emmons (WE) phosphonates. Among the analogues of 1c [R = Me (1a), i-Pr (1b), Bn (1d)], 1a and 1b performed well, although longer reaction times were involved

    PdCl2 catalyzed carbon–carbon bond formation (Heck reaction) between substituted aryl halides and olefins was carried out without a ligand, under irradiation with UV–visible light. The results demonstrated that UV–visible light accelerated the rate of the reaction, leading to an excellent yield of corresponding products. The recovered palladium nanoparticles could be thermally recycled several times. PdCl2 gave excellent conversion up to the fifth addition of substrate.

  • Heterogeneous photocatalysed Heck reaction over PdCl2/TiO2
    作者:Suresh B. Waghmode、Sudhir S. Arbuj、Bina N. Wani
    DOI:10.1039/c3nj40941d
    日期:——
    The heterogeneous PdCl2/TiO2 efficiently catalyzes the C–C bond formation (Heck reaction) between aryliodides and olefins under photochemical and mild reaction conditions. This process gives good to excellent conversion under optimized reaction conditions. After completion of the reaction, Pd2+ is reduced to Pd0. Further, Pd0 can be easily converted into Pd2+ by heating with ammonium chloride at 400 °C for 30 min and the regenerated catalyst could be reused up to the third recycle with good catalytic activity. The catalysts (before and after reaction, as well as regenerated) were systematically characterized using Transmission Electron Microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, temperature programmed reduction and DRUV-visible spectroscopy techniques.
