  使用地球丰富的钴催化剂进行配体和镁活化加氢

  摘要：

  用廉价的地球丰富的金属如钴 (Co) 代替昂贵的贵金属如 Pt、Pd、Ir、Ru 和 Rh，正在吸引更广泛的催化研究兴趣。钴催化剂现在正经历加氢反应的复兴。在此，我们描述了一种使用镁活化的富含地球的 Co 催化剂对多环芳烃 (PAHs) 和烯烃进行加氢的方法。当二酮亚胺用作配体时，CoBr 2的简单且廉价的金属盐与镁结合在温和条件下对具有挑战性的多环芳烃进行位点选择性加氢显示出高催化活性。共催化氢化能够减少多环芳烃的两侧芳烃。多种多环芳烃可以以位点选择性方式进行氢化，这为制备部分还原的多环烃基序提供了一种经济、清洁和选择性的策略，而这些多环烃基序很难通过常规方法制备。还证明了使用定义明确的二酮亚胺配体 Co 配合物作为多环芳烃和烯烃选择性加氢的预催化剂。

  Dilithium amides have been developed as a bespoke and general ligand for iron-catalyzed Kumada–Tamao–Corriu cross-coupling reactions, their design taking inspiration from previous mechanistic and structural studies. They allow for the cross-coupling of alkyl Grignard reagents with sp2-hybridized electrophiles as well as aryl Grignard reagents with sp3-hybridized electrophiles. This represents a rare

  作者：Juan Diego Pizarro、Francisco Molina、Manuel R. Fructos、Pedro J. Pérez

  DOI：10.1002/chem.202001517

  日期：2020.8.12

  A family of phosphine ligands containing a five‐membered ring similar to the popular N‐heterocyclic carbene ligands and an alkoxy third substituent has been developed. These alkoxydiaminophosphine ligands (ADAP) can be generated in one pot and reacted with a copper(I) source leading to the high yield isolation of complexes [(ADAP)CuX]2 (X=Cl, Br). The dinuclear nature of these compounds has been established

  已开发出一个含有五元环的膦配体，该环类似于流行的N杂环卡宾配体，并带有一个烷氧基第三取代基。这些烷氧基二氨基膦配体（ADAP）可以在一个锅中生成，并与铜（I）源反应，从而导致复合物[（ADAP）CuX] 2的高产率分离。（X ＝ Cl，Br）。这些化合物的双核性质已通过X射线研究和DOSY实验确定。对这些配合物从重氮化合物到CH键（烷烃，芳烃），烯烃或NH键的卡宾转移反应的催化性能的筛选，以及在CuAAC或腈转移反应中的性能至少相似（如果不是更好的话），则比他们的（NHC）CuCl类似物好，这些易于调节的ADAP配体为铜催化打开了一个新窗口。

  carbon donor ligands results in reductive elimination. Combined experimental and computational investigations lead to the first evidence of a direct intramolecular C(sp2)–N(sp2) bond formation from a monomeric [(C^N)AuCl2] gold(III) complex. We show that bidentate ligated Au(III) systems bypass transmetallation to form C(sp2)–N(sp2) species and NHC–Au–Cl. Mechanistic investigations of the reported transformation

  双齿Au III –Cl物质[（C ^ N）AuCl 2 ]与双膦或碳供体配体的反应性导致还原消除。联合的实验和计算研究导致从单体[（C ^ N）AuCl 2 ]金（III）配合物直接形成分子内C（sp 2）–N（sp 2）键的第一个证据。我们表明，双齿连接的Au（III）系统绕过金属转移形成C（sp 2）–N（sp 2）物种和NHC–Au–Cl。对所报道的转化的机理研究表明，通过关键的Au III导致配体诱导的还原消除中间的。反应的动力学研究支持二级速率过程。
