  摘要：

  通过使用[1,3-双(二苯基膦基)丙烷]氯化镍{NiCl2(dppp)}作为催化剂研究了芳基氨基磺酸盐和硼酸的SuzukiMiyaura交叉偶联。结果表明，NiCl2(dppp) 是一种高活性的通用催化剂，在低催化剂负载量（通常为 1.01 倍）的情况下，它可以使氨基磺酸芳基酯与略微过量的硼酸（1.2 当量）进行有效的 SuzukiMiyaura 交叉偶联。 .5 摩尔％）。该方法还显示出广泛的通用性，不仅适用于各种氨基磺酸芳基酯，而且适用于一系列硼酸。此外，可以容忍各种官能团。这些明显的优势使 NiCl2(dppp) 成为一种实用且可靠的催化剂体系，用于芳基氨基磺酸酯的 SuzukiMiyaura 偶联。

  function at room temperature. Mechanistic studies on precatalyst activation and the speciation of nickel during catalysis reveal that Ni(I) species are formed in the catalytic reaction via two different pathways: (i) the precatalyst (dppf)Ni(o-tolyl)(Cl) undergoes comproportionation with the active Ni(0) species; and (ii) the catalytic intermediate (dppf)Ni(Ar)(sulfamate) (Ar = aryl) undergoes comproportionation

  对于 Suzuki-Miyaura 偶联反应，镍预催化剂可能是传统钯预催化剂的更可持续的替代品。目前，Suzuki-Miyaura 偶联反应引起了人们极大的兴趣，该反应涉及容易获得的酚类衍生物，例如氨基磺酸芳基酯，因为氨基磺酸酯部分可以作为一个导向基团，用于在交叉偶联之前对亲电子试剂的芳香骨架进行预官能化。通过评估 Ni(0)、(I) 和 (II) 氧化态的配合物，我们报告了一种前催化剂，(dppf)Ni(o-tolyl)(Cl) (dppf = 1,1'-bis(diphenylphosphino)ferrocene )，对于涉及芳基氨基磺酸酯和硼酸的 Suzuki-Miyaura 偶联反应，与其他报道的系统相比，该反应在显着更低的催化剂负载和更温和的反应条件下运行。在某些情况下，它甚至可以在室温下工作。对催化剂前体活化和催化过程中镍形态形成的机理研究表明，Ni(I) 物种在催化反应中通过两种不同的途径形成：(i)

  The iron-catalyzed cross-coupling of aryl sulfamates and tosylates has been achieved with primary and secondary alkyl Grignards. This study of iron-catalyzed cross-coupling reactions also examines the isomerization and beta-hydride elimination problems that are associated with the use of isopropyl nucleophiles. While a variety of iron sources were competent in the reaction, the use of FeF3 center dot 3H(2)O was critical to minimize nucleophile isomerization.

  The first Suzuki-Miyaura cross-coupling reactions of the synthetically versatile aryl O-carbamate and O-sulfamate groups are described. The transformations utilize the inexpensive, bench-stable catalyst NiCl2(PCy3)(2) to furnish biaryls in good to excellent yields. A broad scope for this methodology has been demonstrated. Substrates with electron-donating and electron-withdrawing groups are tolerated, in addition to those that possess ortho substituents. Furthermore, heteroaryl substrates may be employed as coupling partners. A computational study providing the full catalytic cycles for these cross-coupling reactions is described. The oxidative addition with carbamates or sulfamates occurs via a five-centered transition state, resulting in the exclusive cleavage of the aryl C-O bond. Water is found to stabilize the Ni-carbamate catalyst resting state, which thus provides rationalization of the relative decreased rate of coupling of carbamates. Several synthetic applications are presented to showcase the utility of the methodology in the synthesis of polysubstituted aromatic compounds of natural product and bioactive molecule interest.

  The first Suzuki-Miyaura cross-couplings of carbamates, carbonates, and sulfamates is described. The method provides a powerful means of using simple derivatives of phenol as precursors to polysubstituted aromatic compounds, as exemplified by a concise synthesis of the anti-inflammatory drug flurbiprofen.
