Synthesis, characterization and crystal structure of 1-ferrocenesulfonyl-2-long carbon chain alkyl benzimidazole was written by Zhang, Jun-Zhen;Yang, Bin-Qin;Yang, Ya-Ting;Zhang, Bing-Lin. And the article was included in Yingyong Huaxue in 2007.Product Details of 13060-24-7 This article mentions the following:
Six new 1-ferrocenesulfonyl-2-benzimidazole derivatives were prepared from the reaction of ferrocenesulfonyl chloride with benzimidazole derivatives in the presence of dichloromethane and tetrabutylammonium chloride. The reactions of 2-alkylbenzimidazoles [alkyl = Me(CH2)n, n = 5, 6, 7, 8, 10, 14] with ferrocenesulfonyl chloride give 1-ferrocenesulfonyl-2-alkylbenzimidazoles in good yields. The yields of six new ferrocenesulfonyl benzimidazole derivatives were 78-87%. The structures were confirmed by IR, 1H NMR, elemental anal. and MS. The crystal structure was determined via x-ray single crystal diffraction. The compound 1-ferrocenesulfonyl-2-hexylbenzimidazole is the monoclinic system with space group C2/c, and the unit cell parameters are a = 2.825 2(2) nm, b = 0.976 96(7) nm, c = 1.648 28(12) nm, α = 90°, P = 92.053(2)°, γ = 90°, V = 4.546 6(6) nm3, Z = 8, F(000) = 2 024, Mr = 481.40, Dc = 1.407 g/cm3, μ = 0.784 mm-1, R1 = 0.049 5, wR2 = 0.151 7. In the experiment, the researchers used many compounds, for example, 2-Octylbenzimidazole (cas: 13060-24-7Product Details of 13060-24-7).
2-Octylbenzimidazole (cas: 13060-24-7) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Product Details of 13060-24-7
