The asymmetric unit of the title compound, C(8)H(5)F(3)N(2), consists of two half-mol-ecules, one lies on a mirror plane and the other is generated by twofold rotation symmetry, with the axis running through the trifluoro-methyl C atom and the attached benzimidazole C atom. The two 2-trifluoro-methyl-1H-benzimidazole mol-ecules are connected by N-H⋯N hydrogen bonds involving the disordered NH H...
In this study, a new mild steel surface pretreatment solution is introduced based on phosphoric acid containing a benzimidazole derivative as inhibitor. In this way, three different benzimidazole derivatives namely benzimidazole BI, 2-methyl benzimidazole 2MBI and 2-aminobenzimidazole 2ABI were studied in the 1M H3PO4 using DC and AC electrochemical techniques. Results revealed the better corro...
Certain 2-(1'-iminothioimido substituted)-1'-substituted phenybenzoic acids (P(1-9)) were synthesized by reaction of phthalic anhydride with benzotriazole, 2-mercapto benzothiazole and 2-p-amino phenyl benzimidazole, respectively (A(1-3)) followed by imine formation with Schiff bases of thiourea with salicylaldehyde, furfuraldehyde and 1-phenyl-3-methyl-5-pyrazolone. Antiulcer activity was eval...
In the title compound, [CdBr2(C8H8N2)2], the Cd(II) atom has a distorted tetra-hedral coordination formed by the two imino N atoms of two 2-methyl-benzimidazole ligands and two terminal bromide ligands. The Cd(II) atom is slightly out of the benzimidazole planes by 0.320 (3) and 0.210 (3) Å. The dihedral angle between the benzimidazole planes is 71.6 (2)°. In the crystal, mol-ecules are linked ...
The title compound, 0.759C(19)H(21)ClN(2)O(2)S·0.241C(19)H(21)ClN(2)O(2)S, was synthesized by aryl-sulfonyl-ation of 2-n-butyl-5-chloro-1H-benzimidazole in the presence of triethyl-amine. The crystal structure is composed of two mol-ecules, 2-n-butyl-6-chloro-1-(2,4-dimethylphenyl-sulfon-yl)-1H-benzimidazole and 1-(2,4-dimethylphenyl-sulfon-yl)-2-n-butyl-5-chloro-1H-benz-imidazole, in the refin...
Two new molecular structures, namely 1,3-bis(trimethylsilyl)-1H-benzimidazole-2(3H)-thione, C13H22N2SSi2, (2), and 1-trimethylsilyl-1H-benzimidazole-2(3H)-thione, C10H14N2SSi, (3), are reported. Both systems were derived from 1H-benzimidazole-2(3H)-thione. Noncovalent C-H···π interactions between the centroid of the benzmidazole system and the SiMe3 groups form helicoidal arrangements in (2). D...
An environment friendly synthesis of 2-amino-3-cyano-4-aryl-7,7-dimethyl-5-oxo-4H-5,6,7,8-tetrahydrobenzo[b]pyran, 2aryl benzimidazole and 2-aryl-4, 5-dihydro-1H-imidazole derivatives using Mg-Al hydrotalcite as an efficient catalyst has been developed. The excellent efficiency of the catalyst can be attributed to its Lewis acidic sites which resulted in higher reaction yields for different sub...
