  摘要：

  本文介绍了伯胺和仲胺与二芳基碘鎓盐的无过渡金属N芳基化反应。无环和环状胺都具有良好的耐受性，可提供大量的N-烷基苯胺。在无金属方法中，胺的范围，转移吸电子和给电子芳基的能力以及资源的有效利用是无金属方法中前所未有的，因为不需要过量的底物或试剂。

  heterocycles such as indole, carbazole, pyrrole, 10‐phenothiazine, and 10‐phenoxazine were shown to be feasible coupling partners under this catalytic system. The described reaction conditions tolerate a wide range of functional groups and allow an array of aromatic amines as well as unsymmetrical amine products to be easily accessed from the various phenolic derivatives. Interestingly, this catalyst

  提出了使用芳基和杂芳基甲苯磺酸盐对各种胺进行单选择性N-芳基化反应的范围和局限性。空气稳定且易于接近的Pd（OAc）2 / CM-phos CM-phos = 2- [2-（二环己基膦基）苯基] -1-甲基-1 H-吲哚}催化剂体系能够处理各种芳基甲苯磺酸酯底物以及胺亲核试剂，包括伯和仲环状/无环脂族胺和苯胺。在这种催化体系下，含NH的杂环如吲哚，咔唑，吡咯，10-吩噻嗪和10-吩恶嗪被证明是可行的偶联伙伴。所描述的反应条件容许宽范围的官能团，并允许从各种酚衍生物容易地获得一系列的芳族胺以及不对称胺产物。有趣的是，该催化剂体系甚至提供了在水介质中进行反应的机会。我们还报道了旋光性α-中心手性胺与芳基甲苯磺酸盐的分子间偶联，而没有削弱对映体的纯度。

  Two families of biarylphosphine ligands were prepared for use in the Pd-catalyzed amination reaction. The first series investigated was derived from N-phenylpyrroles, and the second, was derived from N-phenylpyrazoles. While the pyrrole ligands were not as general in substrate scope, one of the readily prepared pyrazole ligands (R = t-Bu) was found to have a fairly broad substrate scope.

  phosphorus compound tert-butyl tetraisopropylphosphorodiamidite, prepared from bis(diisopropylamino)chlorophosphine, is an excellent ligand for palladium-catalysed Buchwald–Hartwig amination of aryl- and heteroaryl chlorides and bromides. Based on its ready accessibility and air-stability, this amination protocol is a practical approach to the synthesis of industrially important aryl- and heteroarylamines.

  A new family of pyrazole and bi-pyrazole phosphine ligands are reported that perforin efficiently in the Pd-catalyzed amination reaction. Of the ligands screened, ligand 1 emerged as the most compatible for couplings involving both primary and secondary amines with typical yields of 84-99%. (c) 2006 Elsevier Ltd. All rights reserved.

  Three families of ligands were prepared for use in Pd-catalyzed aryl aminations and possibly other Pd-catalyzed reactions. The first series is derived from diarylsulfones, the second from trityl imidazole, and the third from 2-bromobenzophenone. While these ligands were not very general in terms of substrate scope, they do work fairly well under certain specific conditions. Additionally, the preparation of these ligands is amenable to bulk synthesis. (C) 2004 Elsevier Ltd. All rights reserved.
