An Effective Green Procedure for the Synthesis of Phenacyl Derivatives Catalyzed by Silica-bound 3-{2-[Poly(ethylene glycol)]ethyl}-substituted 1-Methyl-1H-imidazol-3-ium Bromide as a Recyclable Phase Transfer Catalyst under Aqueous Media
Authors
Abstract:
The use of a recyclable phase transfer catalyst, SiO2-PEG-ImBr, is demonstrated in a simple and highly efficient synthesis of phenacyl derivatives by nucleophilic substitution reaction of phenacyl halides with different anions in water. Advantages of this system are easy work-up, moderate to good yields, and recyclable catalyst. The catalyst can be recycled and reused several times with no loss of its efficiency.

In the title compound, C(11)H(12)BrN(2) (+)·Br(-), the imidazole and phenyl rings are nearly perpendicular, making a dihedral angle of 87.71 (7)°. The crystal structure is stabilized by non-classical inter-molecular C-H⋯Br hydrogen bonds and inversion-related mol-ecules are linked through π-π inter-actions between the imidazole ring systems [centroid-centroid distance = 3.472 (6) Å].

1-Methyl-3-(2-oxyethyl)-1H-Imidazol-3-ium-Borate Sulfonic Acid ([MOEI]-BSA) was easily prepared and used as a new and highly efficient solid acid catalyst for the synthesis of benzimidazole derivatives with high isolated yields. Various substituted benzimidazoles were synthesized by a combination of o-phenylenediamines and aldehydes in the presence of [MOEI]-BSA with excellent yields in water a...

The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twof...
