  使用钯/铱双催化剂对苯甲醇衍生物与 CO2 进行可见光羧基化

  摘要：

  双重麻烦：使用Pd/Ir 双催化剂实现了使用 CO 2对苯甲醇衍生物进行高效可见光羧化。由相应的苄醇衍生物可以高效地制备多种苄基羧酸和酯。通过改变 Pd 催化剂，可以在苄基 C-O 和芳基 C-Cl 部分之间进行可切换的位点选择性羧化。

  MnCO3-Catalyzed Transesterification of Alcohols with Dimethyl Carbonate Under Mild Conditions

  摘要：

  Dimethyl carbonate (DMC) is a valuable green reagent with versatile and tunable chemical reactivity and can be used as a raw material for transesterification of alcohols. Herein, MnCO3 was found to be an efficient heterogeneous catalyst for transesterification of various alcohols with DMC and gave desired products under mild conditions. The MnCO3 catalysts were fully characterized by XRD, BET, SEM, TEM, FT-IR and NH3-TPD. The analysis results indicated that MnCO3 calcined at 300 degrees C has significantly enhanced surface area and abundant weak acid sites, which contributed to the superior catalytic performance in the transesterification. Furthermore, deactivation of catalyst resulted from the change of crystal structure and the decrease of weak acid sites. This research expands the potential application for DMC in green chemistry.[GRAPHICS].

• A general Pd-catalyzed α- and γ-benzylation of aldehydes for the formation of quaternary centers
  作者：Ivan Franzoni、Laure Guénée、Clément Mazet

  DOI：10.1039/c5ob00702j

  日期：——

  A palladium-catalyzed benzylation of α-branched aldehydes has been developed using benzyl methyl carbonates. The method gives access to congested quaternary centers in the vicinity of one of the most sensitive carbonyl functionalities and displays unprecedented generality with respect to both coupling partners. Evidence for the direct involvement of a Pd-η3-benzyl intermediate is provided. Extension

  A palladium‐catalyzed cross‐coupling reaction between C(sp) and C(sp3) centers was achieved in excellent yields via C–C bond cleavage and C–O bond cleavage. The method uses benzylic carbonates and also avoids the involvement of benzyl halides, making it more practical in organic synthesis.

  C（sp）和C（sp 3）中心之间的钯催化交叉偶联反应通过C–C键断裂和C–O键断裂以优异的产率实现。该方法使用碳酸苄基酯，并且避免了苄基卤化物的参与，使其在有机合成中更加实用。

  es. In the catalytic cyclization, the internal nucleophile attacks not the ortho-carbon but the para-carbon of the benzylic ester. The [3 + 2] cycloaddition of m-(silylmethyl)benzyl carbonates with alkylidene malonates was developed from the palladium-catalyzed intramolecular SN′-type aromatic substitution.
