So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Qiu, Qi-Ming; Liu, Min; Li, Zhong-Feng; Jin, Qiong-Hua; Huang, Xu; Zhang, Zhen-Wei; Zhang, Cun-Lin; Meng, Qing-Xuan researched the compound: 2-Mercapto-5-methylbenzimidazole( cas:27231-36-3 ).SDS of cas: 27231-36-3.They published the article 《Synthesis, structure, terahertz spectroscopy and luminescent properties of copper(I) complexes with mercaptan ligands and triphenylphosphine》 about this compound( cas:27231-36-3 ) in Journal of Molecular Structure. Keywords: preparation copper mercaptothiazole phosphine complex; crystal structure copper mercaptothiazole phosphine complex; fluorescence copper mercaptothiazole phosphine complex. We’ll tell you more about this compound (cas:27231-36-3).
The reactions of Cu(I) halides with PPh3 (PPh3) and mercaptan ligand [2-mercapto-6-nitrobenzothiazole (HMNBT), 2-amino-5-mercapto-1,3,4-thiadiazole (HAMTD) and 2-mercapto-5-methyl-benzimidazole (MMBD)] yielded seven complexes, [CuCl(HMNBT)(PPh3)2] (1), [CuX(HMNBT)(PPh3)]2 (X = Cl, Br) (2-3), [Cu(MNBT)(HMNBT)(PPh3)2] (4), [CuBr(HAMTD)(PPh3)2]·MeOH (5) and [CuX(MMBD)(PPh3)2]·2MeOH (X = Br, I) (6-7). These complexes were characterized by elemental anal., x-ray diffraction, 1H NMR and 31P NMR spectroscopy. In these complexes the mercaptan ligands act as monodentate or bridged ligand with S as the coordination atom. In complexes 1 and 4, H bonds CH···X and weak interactions CH···π give chains and 2-dimensional network, resp., while complexes 2 and 3 are dinuclear. In 5-7, intramol. H bonds link the [CuX(thione)(PPh3)2] mols. and the solvated MeOH mols. into centrosym. dimers. Complexes 1-5 represent 1st Cu(I) halide complexes of HMNBT and HAMTD. The complexes 1, 5, 6 and 7 exhibit interesting fluorescence in the solid state at room temperature and their terahertz (THz) time-domain spectroscopy was also studied.
This compound(2-Mercapto-5-methylbenzimidazole)SDS of cas: 27231-36-3 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
