  钯在室温下通过裂解C‑O键的方式催化芳基磺酸盐的还原均偶联反应

  摘要：

  在温和条件下已成功实现了钯催化的芳基磺酸盐还原均偶联反应。这种转变是芳基磺酸盐在室温下通过C-O键断裂的均偶联反应的新方法，从而提供了对称性联芳基的另一种合成方法。所报道的还原性均偶联反应对许多常见的官能团均具有耐受性，而与给电子或吸电子性质无关，这使得这种新近发展的转变对于补充乌尔曼偶联很重要。

  日期：2021.1.15

  A generalized protocol for the reductive carbonylation of (hetero) aryl halides and triflates under CO gas‐free conditions using Pd/Co2(CO)8 and triethylsilane has been developed. The mild reaction conditions, enhanced safety, and wide substrate scope highlight its importance in routine organic synthesis.

  The present invention provides an activator in arylamination using a palladium compound as a catalyst, which is superior to conventional phosphines in stability and performance. With the phosphine sulfide as an activator, an arylamination reaction achieves improved selectivity to produce a desired aromatic amine in an obviously increased yield as compared with a reaction using the corresponding phosphine compound. Moreover, the phosphine sulfide of the invention is impervious to oxidation and exists stably in air and therefore sufficiently withstands use on an industrial scale.

  本发明提供了一种在芳基化反应中使用钯化合物作为催化剂的活化剂，其在稳定性和性能方面优于传统的膦化合物。通过使用膦硫化物作为活化剂，芳基化反应实现了改善的选择性，以明显增加的产量生产所需的芳香胺，与使用相应的膦化合物的反应相比。此外，本发明的膦硫化物不受氧化影响，在空气中存在稳定，因此足以在工业规模上使用。

  Phenols were vinylated at the ortho-position with ethyne in the presence of SnCl(4)-Bu(3)N reagent. The reaction was applicable to phenols possessing either electron-donating or electron-withdrawing groups. 2,6-Divinylphenols were synthesized under modified conditions. A reaction mechanism involving carbostannylation of alkynyltin and phenoxytin was discussed.

  We have developed a catalytic electron transfer (ET) system composed of a transition metal ate complex (Me3M(II)Li; M = Co(II), Mn(II), Fe(II)) and magnesium. This system (catalytic Me3M(II)Li/Mg) turned out to be effective for various ET reactions, such as the desulfonylation of N-phenylsulfonyl amides, and others (the chemoselective cleavage of O-allyl groups, the reduction of nitro groups, the partial

  我们开发了一种催化电子转移 (ET) 系统，由过渡金属盐络合物 (Me3M(II)Li；M = Co(II)、Mn(II)、Fe(II)) 和镁组成。该系统（催化 Me3M(II)Li/Mg）被证明对各种 ET 反应有效，例如 N-苯基磺酰胺的脱磺酰化，以及其他（O-烯丙基的化学选择性裂解、硝基的还原、二酮的部分还原，以及二苯基碘盐的还原偶联）。该系统的 ET 能力可以通过改变 ate 配合物的配体来调整。实验和电化学证明了这种可调性：烷氧基连接和双阴离子型 ET 复合物分别显示减弱和增强的还原能力。ET 能力的改变通过电化学测量和化学反应进行评估。这些结果为设计各种定制的 ET 复合物提供了基础。
