  Oxyfunctionalization of Aliphatic Esters by Methyl(trifluoromethyl)dioxirane

  摘要：

  The oxidation of lineal, cyclic, and bicyclic aliphatic p-chlorobenzoic and p-chorobenzenesulfonic acid esters 2 with methyl(trifluoromethyl)dioxirane (TFDO) (1) occurs at positions in the hydrocarbon chain distant from the directing group with a significant degree of selectivity to give the corresponding keto or hydroxy esters. Compounds 2 are relatively deactivated with respect to this oxidation due to the electron-withdrawing nature of the ester moiety. Methylene C-alpha-H and C-beta-H bonds remain unchanged in all cases, but tertiary C-beta-H bonds undergo oxidation with TFDO (1). Stereoelectronic factors are used to explain the faster reaction rate in competition experiments for the oxidation of endo-norbornyl ester 2h than for its exo-isomer 2g.

  Palladium-Catalyzed Alkoxycarbonylation of Arylsulfoniums

  摘要：

  Alkoxycarbonylation of arylsulfoniums has been developed with the aid of a catalytic amount of a palladium-Xantphos complex under an atmospheric pressure of CO gas. Various functional groups such as carbonyl, cyano, halo, and sulfonyl groups were well tolerated under the present catalysis. Since aryldimethylsulfoniums were readily prepared from the corresponding aryl methyl sulfides and methyl triflate, one-pot alkoxycarbonylation of aryl methyl sulfides could be accomplished.

• Practical in situ-generation of phosphinite ligands for palladium-catalyzed carbonylation of (hetero)aryl bromides forming esters
  作者：Lin Wang、Helfried Neumann、Anke Spannenberg、Matthias Beller

  DOI：10.1039/c7cc02828h

  日期：——

  An effective method for alkoxycarbonylation of (hetero)aryl bromides is developed in the presence of in situ-generated phosphinite ligands tBu2POR (R = nBu, nPr, Et or Me). For this purpose commercially available tBu2PCl was used as the pre-ligand in the presence of different alcohols. For the first time cross coupling reactions with two alcohols – one generating the ligand, the other used as substrate

  在原位生成的次膦酸酯配体t Bu 2 POR（R = n Bu，n Pr，Et或Me）存在下，开发了一种用于（杂）芳基溴的烷氧羰基化的有效方法。为此目的，在不同醇存在下，将可商购的t Bu 2 PC1用作预配体。首次开发了与两种醇的交叉偶联反应-一种生成配体，另一种用作底物。通过这种方法，可以以更有效的方式进行配体优化，并且可以以良好的产率和选择性获得所需的产物。

  日期：2008.5.1

  The conversion of ketones to esters has been achieved through the use of Cu catalyst and tetrabutylammonium nitrite. This reaction involves the activation of the less activated C-C bond, and the alkyl group is removed as a leaving group. Various isopropyl ketones are found to be good substrates for this reaction.

  method for the carbonylation of (hetero) aryl pentafluorobenzenesulfonates and triflates under exceptionally mild conditions using palladium/dicobalt octacarbonyl [Pd/Co2(CO)8] has been developed. Besides acting as carbon monoxide (CO) source, Co2(CO)8 enhances the reaction rate by accelerating the CO insertion through an in situ generated bimetallic palladium cobalt tetracarbonyl [Pd‐Co(CO)4] complex

  已经开发了一种在异常温和的条件下使用钯/二钴八羰基[Pd / Co 2（CO）8 ]对（杂）芳基五氟苯磺酸盐和三氟甲磺酸酯进行羰基化的有效方法。除了充当一氧化碳（CO）源外，Co 2（CO）8还可以通过原位生成的双金属钯四羰基钴[Pd-Co（CO）4）加速CO的插入，从而提高反应速率。] 复杂的。在优化的反应条件下，各种活化和失活的，以及位阻和杂芳族底物的羰基化反应在室温下均能有效进行。生物学上相关的异古瓦汀和拉扎贝米中间体的高化学选择性和改进的合成方法突出了其作为有价值的合成方法的范围。该协议的通用性进一步扩展到其他亲电试剂（溴化物，氯化物和甲苯磺酸盐）。

  The Cu-catalyzed aerobic oxidative esterification of simple ketones via C-C bond cleavage has been developed. Varieties of common ketones, even inactive aryl long-chain alkyl ketones, are selectively converted into esters. The reaction tolerates a wide range of alcohols, including primary and secondary alcohols, chiral alcohols with retention of the configuration, electron-deficient phenols, as well
