  Pd / Cu催化末端炔烃的交叉偶联在室温下合成不对称的1,3-二炔

  摘要：

  通过在氧存在下使用3-（二苯基膦基）丙酸作为配体，通过两个不同的末端炔烃的PdCl / CuI催化的氧化偶合，开发了一种不对称的1,3-二炔的简便实用的合成路线。该系统不仅适用于芳族炔烃，还适用于杂芳族和脂族炔烃，它们在室温下以中等至良好的收率转化成相应的不对称1,3-二炔。此外，不对称的1,3-二炔也以克为单位获得。机理研究表明，氧气在催化循环中起关键作用。

  for the homo- & cross-coupling of terminal alkynes. Excellent functional group tolerance and good yields were observed with oxygen as an oxidant in an isopropanol solution (or as additive) under ambient conditions. Furthermore, the composite catalyst shows good recyclability and can be recovered simply and reused several times without significant loss in its catalytic activities.

  AbstractCu complexes supported on metal‐organic frameworks (MOFs) with N1,N1,N2,N2‐tetramethylethylenediamine (TMEDA) were prepared via post‐synthetic modification, and proved to be highly efficient for Glaser heterocoupling reactions. Compared with some referential catalysts, which were prepared by using a series of copper salts and Cu0 nanoparticles as the copper sources, the newly designed MIL‐101‐NH‐TMEDA⋅CuClx exhibited highest catalytic activity and selectivity in the model Glaser heterocoupling reaction. Much lower activity was observed with the homogeneous counterpart, TMEDA⋅CuCl4. Intriguingly, the Glaser heterocoupling reactions over MIL‐101‐NH‐TMEDA⋅CuClx catalyst can be conducted without adding external ligands, base, or acid, which are always necessary in the previously reported systems. The dense catalytic active sites in the MOF channels and the adsorption properties of the MOF were conjectured to be partially responsible for the observed high catalytic activity, which may allow the formation of a unique internal environment in the three‐dimensional porous framework that significantly boosted progress of the reactions. The X‐ray photoelectron spectroscopy (XPS) results showed also that the catalytically active copper species changed from CuII to CuI after catalytic use.
