  Heteroaryl-substituted arenes and heteroarenes were efficiently amidated through ruthenium-catalyzed C–H bond functionalizations with a variety of sulfonyl azides. Particularly, cationic ruthenium(II) complexes proved to be most effective and allowed nitrogenations of electron-rich and electron-deficient arenes with ample substrate scope.

  A simple, sustainable, efficient, mild, and low‐cost protocol was developed for d‐glucose‐assisted Cu‐catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen‐containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because

  A series of N-aryl and N-heteroaryl pyrazoles have been deproto-metallated using a 2,2,6,6-tetramethylpiperidino-based mixed lithium–zinc combination. Mono-, di-, and tri-iodides have been obtained after subsequent trapping with iodine, depending on the substrate and on the quantity of base used. The results have been discussed in the light of the CH acidities of the substrates, determined both in the gas phase and in THF solution using the DFT B3LYP method.

  2-cyclohexenediamine), and (Salph)Cu (salph = N, N’-bis(salicylidene)-1,2-phenylenediamine) were synthesised and evaluated as catalysts for the N-arylation of pyrazole with aryl halides. A variety of aryl iodides and bromides underwent coupling with pyrazole, promoted by the (Saldch)Cu complex, in moderate to excellent yields without the protection by an inert gas.

  solubility alone does not explain the performance of organic ionic bases in the room‐temperature coupling of aryl iodides and even bromides with aliphatic and aromatic amines and N‐heterocycles (NuH; see scheme). Conductivity measurements show that these organic ionic bases, which contain tetraalkylammonium or ‐phosphonium cations, are readily ionized in organic solvents.

  仅仅良好的溶解度并不能解释有机离子碱在芳基碘化物甚至溴化物与脂族和芳族胺以及N杂环的室温偶联中的性能（NuH；参见方案）。电导率测量表明，这些含有四烷基铵或阳离子的有机离子碱在有机溶剂中很容易被电离。
