Reported herein is an asymmetric Pd/PC-Phos-catalyzed denitrogenative cyclization of benzotriazoles with allenes and N-allenamides, representing the first example of enantioselective denitrogenative cyclizations of benzotriazoles. A series of optically active 3-methyleneindolines were obtained in good yields with high ee values. The use of inexpensive and readily available starting materials, high regio- and enantioselectivity, a broad substrate scope, mild reaction conditions, no need for base, as well as versatile functionalization of the 3-methyleneindolines make this approach attractive.

A new tridentate benzimidazole ligand (L-C11) containing undecyl chains and its Mn (II) and Zn (II) complexes were synthesised and characterized by spectroscopic and analytical methods. Molecular structures of complexes [Mn(L-C11)Cl2] and [Zn(L-C11)Cl2] were evaluated by X-ray diffraction studies. The X-ray data showed metal ions in both complexes are five-coordinate with distorted square pyramidal geometry around the metal centres. The undecyl chains in the structure of the complexes are aligned in an interdigitated manner (head to tail) forming a non-polar domain. The aggregation properties of the ligand and its complexes were investigated by UV?Vis. absorption and emission spectroscopies in DMF-water mixtures. The emission spectral data revealed that the compounds showed aggregation induced quenching (AIQ) in DMF-water solutions. Moreover, thermal properties of the compounds were investigated by TG, DTG and DSC analysis.

Among cross-coupling reactions, the Suzuki-Miyaura transformation stands out because of its practical advantages, including the commercial availability and low toxicity of the required reagents, mild reaction conditions, and functional group compatibility. Nevertheless, few conditions can be used to cross-couple alkyl boronic acids or esters with aryl halides, especially 2-pyridyl halides. Herein, we describe two novel Suzuki-Miyaura protocols that enable selective conversion of polychlorinated aromatics, with a focus on reactions to convert 2,6-dichloropyridines to 2-chloro-6-alkylpyridines or 2-aryl-6-alkylpyridines.

Interlocked dimer 2, which is composed of two physically interlocked monomers 1, has three cavities (cavity A × 2 and cavity B × 1) and can encapsulate three anions, such as NO3 – and BF4 -, one anion per cavity. There are six possible encapsulation patterns, A-F; two (A and F) contain only one kind of anion and the others (B-E) contain both NO3 – and BF4 – at the same time with different ratios and with different positions. Anion competition experiments showed that in addition to F, which encapsulates three NO3 – ions, C, in which NO3 – and BF4 – ions are captured in cavities A and cavity B, respectively, was selectively formed. Detailed investigations have revealed that B-E were formed by dimerization, but three of the four were subjected to anion exchange and converged into C or F. This selective formation can be explained by the fact that NO3 – is a better anion template than BF4 -, as well as the molecular structure of the interlocked dimer; cavities A are surrounded by four bridging ligands and can be accessed by free anions, whereas no space available for anion exchange is present around cavity B because this cavity is surrounded by eight bridging ligands. Therefore, the BF4 – ions in cavities A are expelled by free NO3 -, but the BF4 – ion in cavity B is not, resulting in the selection of C and F. We have found that the volume of the cavity influenced anion recognition. New interlocked dimer 3, which has smaller cavities than those of 2, captured three NO3 – ions to form F, whereas only a small amount of an interlocked dimer that contains both NO3 – and BF4 – was formed.
