• Iridium–CNP complex catalyzed cross-coupling of primary alcohols and secondary alcohols by a borrowing hydrogen strategy

  A highly efficient C–C bond formation has been developed through the cross-coupling of primary and secondary alcohols. The corresponding functionalized ketones were obtained with an iridium–CNP complex as a catalyst through the borrowing hydrogen strategy. The present methodology provides an easy alternative method to aldol reaction derivatives. More importantly, the complexes were also effective catalysts for the alkylation of an aromatic amine with a tertiary alkyl amine.

  通过伯醇和仲醇的交叉耦合，开发了一种高效形成碳-碳键的方法。利用铱-CNP配合物作为催化剂，通过借氢策略，获得了相应的功能化酮类化合物。目前的方法为aldol反应衍生物提供了一种简便的替代方法。更重要的是，这些配合物在芳香胺与叔�胺的烷基化反应中也是有效的催化剂。

  The α-alkylation of ketones with primary alcohols was realized by CC cross-coupling with iridium–CNP complexes as catalyst. This reaction proceeds via dehydrogenation reactions, aldol condensation, and hydrogenation using the borrowed hydrogen atoms from alcohols. The pyridyl methanols and other heterocyclic substituted methanols, especially alkyl alcohols, were also suitable for this transformation

  酮与伯醇的α-烷基化是通过铱-CNP络合物作为催化剂的C C交叉偶联实现的。该反应通过脱氢反应，醇醛缩合和使用从醇中借来的氢原子进行氢化而进行。吡啶基甲醇和其他杂环取代的甲醇，尤其是烷基醇，也适用于该转化。
• Vinyl Azides as Radical Acceptors in the Vitamin B₁₂-Catalyzed Synthesis of Unsymmetrical Ketones

  Vinyl azides are very reactive species and as such are useful building blocks, in particular, in the synthesis of N-heterocycles. They can also serve as precursors of ketones. These form in reactions of vinyl azides with nucleophiles or radicals. We have found, however, that under light irradiation vitamin B12 catalyzes the reaction of vinyl azides with electrophiles to afford unsymmetrical carbonyl

  乙烯基叠氮化物是非常活泼的物质，因此是有用的结构单元，特别是在N-杂环的合成中。它们还可以作为酮的前体。这些是在乙烯基叠氮化物与亲核试剂或自由基的反应中形成的。然而，我们发现，在光照射下，维生素 B 12催化乙烯基叠氮化物与亲电子试剂的反应，以良好的产率提供不对称羰基化合物。机理研究表明烷基自由基是这种转变的关键中间体。
• Synthesis, Structures of Benzoxazolyl Iridium(III) Complexes, and Applications on C–C and C–N Bond Formation Reactions under Solvent-Free Conditions: Catalytic Activity Enhanced by Noncoordinating Anion without Silver Effect
  作者：Dawei Wang、Keyan Zhao、Chongying Xu、Hongyan Miao、Yuqiang Ding

  DOI：10.1021/cs5009909

  日期：2014.11.7

  Several new bisbenzoxazolyl iridium(III) complexes have been synthesized and characterized through X-ray crystallography. These complexes exhibit excellent catalytic activity in CC and CN bond formation reactions from the alkylation of amine with amine, amine with alcohol, ketone with alcohol, and alcohol with alcohol through a borrowing hydrogen reaction. Moreover, these iridium(III) complexes are effective catalysts for the alkylation of amine with alcohol and ketone with alcohol under solvent-free conditions. The catalytic activity of these complexes is greatly enhanced by noncoordinating, while the experiments have excluded the possibility of a silver effect (bimetallic catalysis or silver-assisted metal catalysis) from the experiments.

  A cyclometalated iridium(III) complex containing a N∧C∧N-coordinating terdentate ligand [Ir(dpyx-N,C,N)Cl(μ-Cl)]2 was found to be a general and highly effective catalyst for the α-alkylation of ketones and N-alkylation of amines with alcohols. In the presence of catalyst (1 mol % Ir) and base (0.2–0.5 equiv), a variety of desirable products were obtained in good yields under an air atmosphere. Notably
