• A Simple and Improved Procedure for the Conversion of Alkynes to 1,2-Diketones by Indirect Electrooxidation With Ruthenium Tetroxide as a Mediator

  Indirect electrooxidation of alkynes 1 using ruthenium tetroxide as a mediator, leading to 1,2-diones 2 in 72-87%, is described. The electrolysis is carried out in the presence of a catalytic amount of ruthenium dioxide dihydrate in a two phase system of saturated aqueous sodium chloride and carbon tetrachloride. The overoxidation of 1,2-diones to the corresponding carboxylic acid, an unavoidable drawback generally encountered in the metal oxidation of acetylenes, is suppressed greatly by maintaining the pH of the aqueous phase at 4 and conducting the reaction at 0-5°C. The synthetic utility of this electrochemical oxidation is exemplified by the preparation of 2i (82%), a key intermediate for the synthesis of furaneol 4, from the commercially available 1i.

  使用四氧化钌作为介质，对炔烃1进行间接电氧化，以72-87%的产率得到1,2-二酮2。电解在含有催化量二氧化钌二水合物的水和四氯化碳两相体系中进行，使用饱和氯化钠水溶液。通过将水相的pH维持在4，并在0-5°C下进行反应，可以大大抑制1,2-二酮过氧化成相应的羧酸，这是通常在金属氧化炔烃中遇到的一个不可避免的缺点。这种方法的合成实用性通过从市售的1i制备关键中间体2i（产率82%）来证明，2i是合成furaneol 4的重要中间体。

  A Ni(II)-catalyzed unconventional Meyer–Schuster rearrangement (MSR) is paired with cross-coupling through inner-sphere acyloxy migration. Various propargyl acetates react with aryl boronic acids, leading to the formation of a range of α-arylated enone derivatives. This transformation is enabled by the use of a P∧N-type phosphinooxazoline (PHOX) ligand, which allows the substrate to coordinate with

  Ni(II) 催化的非常规迈耶-舒斯特重排 (MSR) 通过内球酰氧基迁移与交叉偶联配对。各种乙酸炔丙酯与芳基硼酸反应，形成一系列 α-芳基化烯酮衍生物。这种转变是通过使用 P ∧ N 型膦基恶唑啉 (PHOX) 配体实现的，该配体允许底物与方形平面 Ni(II) 中心配位。它引发炔部分的芳基镍化，然后进行乙酸基团的分子内转位。这种非经典方法允许在 α 位添加富电子亲核试剂，而不需要氧化还原添加剂。一系列对照实验包括18O同位素标记研究和计算分析证实了内球酰氧基迁移。

  A direct and convenient approach for the coupling of propargylic substrates with diphenylphosphine oxide in the presence of Tf2O and 2,6-lutidine has been developed. The method provides a general approach for the construction of attractive allenylphosphoryl skeletons with high atom and step economy under metal free conditions.
