The title compound, C24H21N3O3, crystallizes with two unique but closely r.m.s. overlay fit = 0.215 A˚) comparable molecules (1 and 2) in the asymmetric unit of the triclinic unit cell. In molecule 1, the dihedral angles between the central imidazlole ring and the benzene-ring substituents are 42.51 (9), 45.41 (9) and 56.92 (8), respectively. Comparable data for molecule 2 are ...

The title compound, C24H21ClN2O, crystallizes with two unique molecules in the asymmetric unit. In each molecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each molecule has a propan-2-ol substituent. In the crystal, a series of ... Read more

Here, we reported two methods for the synthesis of multi-substituted imidazoles,firstly via four-component cyclocondensation reaction of benzil, aliphatic amines (allylamine or pentylamine), and aromatic aldehyde and ammonium acetate. Using an ionic liquid catalyst namely, diethyl ammonium hydrogen sul-fate, and under solvent-free conditions. Secondly, via the alkylation of synthesized NH imidazoles with alkyl halide (allyl bromide and pentyl bromide) gave8a–cin high ... Read more
