The mol-ecule of the title compound, C(26)H(18)N(4), resides on a crystallographic inversion centre with a dihedral angle of 44.94 (5)° between the benzimidazole ring system and the benzene ring. The primary hydrogen bond is C-H⋯N and inversion-related pairs of these generate a chain of rings along the c-axis direction; π⋯π stacking involving the benzimidazole groups with inter-planar separatio...

in this article, simple, convenient synthesis of 2-aryl-1-arylmethyl-1h-1,3-benzimidazole (1,2-disubstitutedbenzimidazoles) via condensation of 1,2-phenylenediamine and aromatic aldehydes using sba-pr-so3h as a nanoporous solid acid catalyst in green protocol was reported.

The Front Cover shows that compound 9a (in golden rod sticks), the benzimidazole bioisoster of azobenzene-containing BET inhibitor MS436, preferentially binds to first (BD1, in orange red) over second (BD2, slate blue) bromodomain family members. In this study, bioisosteric replacement azobenzene moiety selective inhibitors with a ring afforded set benzimidazole-6-sulfonamides. Evaluation bindi...

Benzimidazole has been studied previously by certain investigators as a growth regulator. This compound was found to promote various phases of growth in the gametophyte of the fern Thelypteris felix-mas. Concentrations of benzimidazole in the order of 0.01 mm, 0.02 mm, and 0.1 mm stimulated cell division, an increase in body size, and also rhizoid lengths of the gametophyte. A concentration of ...

In the title mol-ecular salt, C(26)H(28)N(4) (2+)·2Br(-), the central benzene ring makes dihedral angles of 76.75 (11) and 82.40 (10)° with the pendant benzimidazole rings. The corresponding angle between the benzimidazole rings is 57.03 (9)°. In the crystal, the cations and anions are linked via C-H⋯Br hydrogen bonds, forming sheets lying parallel to the bc plane. The crystal structure also fe...

A new benzimidazole compound, C(12)H(14)N(2)O(2), has been synthesized by the reaction of 2-methyl-1H-benzimidazole and ethyl 2-bromo-acetate. In the crystal structure, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains. π⋯π Contacts (centroid⋯centroid distance = 3.713 Å) are observed. A C-H⋯π inter-action is also present. The N-C-C-O torsion angle is 178.4 (2)°.

The whole mol-ecule of the title compound, C(20)H(18)N(4)O(4), is generated by an inversion center. The benzimidazole ring mean plane make a dihedral angle of 89.4 (8)° with the plane passing through the acetate group (COO). In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance = 3.743 (3) Å] involving inversion-related benzimidazo...
