2-(4-Bromophenyl)-1-ethyl-1H-1,3-benzodiazole
In the title compound, C(15)H(13)BrN(2), the benzimidazole group is almost planar, as indicated by the dihedral angle of 2.6 (3)° between the best planes through the benzene and imidazole rings. The best plane through the attached benzene makes an angle of 44.5 (2)° with the best plane through the benzimidazole system. C-H⋯π inter-actions are observed in the crystal structure.
متن کاملEthyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate
This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...

In the title compound, C(22)H(21)BrN(4)O(2)·H(2)O, the two pyrazole rings are essentially planar [maximum deviations 0.002 (1) and 0.002 (1) Å], and form a dihedral angle of 73.46 (9)°. The dihedral angle between the benzene rings is 29.33 (7)°. In the crystal, mol-ecules are connected via C-H⋯O and O-H⋯N hydrogen bonds, forming layers in the ab plane.

In the crystal of the title compound, C(10)H(12)BrNO, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Further N-H⋯O hydrogen bonds link the dimers into sheets propagating in (100).

In the title compound, C(22)H(17)BrN(2)O(2), the benzimidazole ring system is essentially planar, with a maximum deviation of 0.017 (1) Å, and forms dihedral angles of 27.79 (6) and 64.43 (6)° with the phenyl and bromo-substituted benzene rings, respectively. In the crystal, mol-ecules are linked into one-dimensional chains along the a axis by weak C-H⋯O hydrogen bonds. Weak inter-molecular C-H...
