“…The UV-Vis spectrum of 3 showed three absorption maxima at 262, 294 and 324 nm. The observed broad maximum at 345 nm could be attributed to the n-π* transition of the azomethine group while the bands at 262 and 294 nm refer to the π-π* transitions in the UV-Vis spectrum of 3 (28). (1) and the appearance of new peaks in aromatic region at 8.47 ppm and 8.37 ppm belongs to the imine protons and the -NH peak at 10.92 ppm shows that the imine condensation reaction has occurred.…”

In this study, we synthesized a novel benzimidazole-based Schiff base; (E)-4,4'methylenebis(2-((E)-(((1H-benzo[d]imidazol-2-yl)methyl)imino)methyl)phenol) (3) was synthesized by the condensation of 5,5'-methylenebis(2-hydroxybenzaldehyde) (1) and (1H-benzo[d]imidazol-2yl)methanamine.HCl salt (2). This Schiff base derivative was reported for the first time and fully characterized by common spectroscopic techniques. Absorption and fluorescence spectroscopy were recorded to determine the sensing ability of 3 towards metal ions. Selectivity to Zn 2+ ion among studied other cations was detected. The crystal structure of 2, C8H13Cl2N3O, has been determined by single crystal X-ray diffraction method. The crystal structure of the title compound, C8H11N3 2+ 2(Cl-)H2O, consists of an organic 1H-benzoimidazol-3-ium (C8H11N3 2+) cation, an inorganic 2(Cl-) anion and one water (H2O) molecule. In the cation of studied compound, C8H11N3 2+ , the benzimidazole ring is almost planar with a maximum deviation of-0.012 (3) Å. The molecule crystallized in the monoclinic structure and the space group P21/c. The crystalline stacking structure is stabilized by intramolecular N-H•••Cl, N-H•••O, the intermolecular N-H•••Cl hydrogen bond interactions connection the molecules into a two dimensional network and between anions and the water molecules. π-π interaction between benzimidazole rings [centroid-centroid lengths = 3.4642 (2) Å, 3.5309 (2) Å and 3.5527 (2) Å] may further stabilize the structure.

A one‐pot four‐component synthesis of 6‐aryl‐6H‐dibenzo[e,i][1,3,7,2]oxadiazaborecin‐8(7H)‐ones is described. Heating a mixture of isatoic anhydride and a benzylamine afforded the corresponding anthranilamide derivative, which was condensed with a 2‐hydroxybenzaldehyde and an arylboronic acid under solvent‐free conditions to produce bridgehead bicyclo[4.4.0]‐boron heterocycles in good to excellent yields. Single‐crystal X‐ray analysis conclusively confirms the structures of the obtained bridgehead bicyclic 6–6 heterocyclic compounds.

“…Thus O, N, P and also S atoms can coordinate to a boron atom to obtain various structures. 12,3,4,9,13,14 In addition, since boron has a similar atomic size to carbon, it allows us to investigate alloying experiments on the hydrogenation properties of TiFe. 15 Biological research has also increased over last few decades due to its application in cancer treatment.…”
