  三苯基膦介导的活化炔烃的金催化部分加氢

  摘要：

  金（I）可以显示出与三苯基膦的协同作用，从而加速了三苯基膦介导的活化炔烃的部分氢化。在该方案中，当芳基环带有电子给体取代基时，3-芳基丙酸酯被选择性地还原为Z-异构体，而3-芳基丙炔酮被还原为E-异构体。

• Generation of Phosphoranes Derived from Phosphites. A New Class of Phosphorus Ylides Leading to High <i>E</i> Selectivity with Semi-stabilizing Groups in Wittig Olefinations

  Tosylhydrazones derived from aryl aldehydes react with t-BuOK, ClFeTPP, (MeO)3P, and aldehydes to furnish olefins with high E selectivity. These reactions occur through a Wittig-type pathway via the corresponding diazo compounds, metal carbenes and phosphorous ylides, with the water-soluble trimethyl phosphate as the byproduct. Similar reactions can also be performed using ethyl diazoacetate; however

  源自芳基醛的甲苯磺酰腙与 t-BuOK、ClFeTPP、(MeO)3P 和醛反应以提供具有高 E 选择性的烯烃。这些反应通过相应的重氮化合物、金属卡宾和磷叶立德通过 Wittig 型途径发生，副产物为水溶性磷酸三甲酯。使用重氮乙酸乙酯也可以进行类似的反应；然而，仅在 LiBr 存在下才观察到高 E 选择性。在这种情况下，该反应被认为是通过通过 Arbuzov 反应形成的膦酸阴离子发生的。因此，该烯化反应通过 Horner-Wadsworth-Emmons (HWE) 反应发生，但膦酸阴离子是在完全无碱的条件下生成的。

  The commercially available Fe(III) and Ru(II) porphyrin complexes Fe(TPP)Cl and Ru(TPP)(CO) are efficient catalysts for selective olefination of a variety of aldehydes with ethyl diazoacetate in the presence of triphenylphosphine. The reactions were carried out under mild conditions in a one-pot fashion with the use of a stoichiometrical amount of EDA, which proceeded with excellent yields and high

  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.

• Task-Specific Ionic Liquid as Reagent and Reaction Medium for the One-Pot Horner–Wadsworth–Emmons–Type Reaction Under Microwave Irradiation
  作者：Hassan Valizadeh、Abbas Shockravi

  DOI：10.1080/00397910902898650

  日期：2009.11.18

  A task-specific imidazolium-based phosphinite ionic liquid (IL-OPPh2) was used as the dual solvent-reagent for the synthesis of E-cinamates and coumarin derivatives via the one-pot Horner-Wadsworth-Emmons-type reaction. The ionic liquid containing its corresponding phosphinite moiety was reacted with a-chloro esters and benzaldehyde or salicylaldehyde derivatives in the presence of sodium methoxide under microwave irradiation to produce the related E-cinamates or coumarins, respectively. The satisfactory results were obtained with good yields, short reaction time, and simple experimental procedure.
