Preparation method for 2,4,5-trisubstituted imidazole compound

The invention relates to a preparation method for 2,4,5-trisubstituted imidazole. According to the method, benzylamine is used as a substrate, and ZnIn2S4 is used as a photocatalyst; and under the condition of illumination of visible light, benzylamine un

A Porous Organic Poly(triphenylimidazole) Decorated with Palladium Nanoparticles for the Cyanation of Aryl Iodides

A new porous organic poly(triphenylimidazole), PTPI-Me, was prepared through a Yamamoto self-coupling reaction of 2,4,5-tris-(4-bromophenyl)-1-methyl-1H-imidazole (TPI-Me) in the presence of bis(1,5-cyclooctadiene)nickel(0). The polymer was subsequently decorated with Pd nanoparticles (NPs) to afford a heterogeneous cyanation catalyst, Pd@PTPI-Me. Pd NPs with an average diameter of 2.7 nm were grown within the PTPI-Me framework, owing to the coordination of the imidazole rings to the Pd species. The resultant Pd@PTPI-Me catalyst, with a Pd loading of 0.13 mmol g?1, exhibited superior catalytic activity for the cyanation of aryl iodides. More importantly, the heterogeneous catalyst was also readily recycled and displayed negligible deactivation after five cycles.

Efficient synthesis of 2,4,5-triaryl-1H-imidazoles from aromatic aldehydes with HMDS catalyzed by N-bromosaccharin (NBSa)

A one-pot efficient procedure for the synthesis of 2, 4, 5-triaryl-1H-imidazole derivatives by the reactions of hexamethyldisilazane and arylaldehydes in the presence of N-bromosaccharin (NBSa) is studied. This new method offers several advantages, such as excellent yields, easy workup, short reaction times, and simple procedure.

Regioselective synthesis of cis- and trans-2,4,5-triarylimidazolines and 2,4,5-triarylimidazoles from available reagents

Novel data were obtained concerning the reaction of aromatic aldehydes with ammonia. A preparative method for the synthesis of new substituted 1,3,5-triaryl-2,4-diazapenta-1,4-dienes was developed. These products are the starting reactants for syntheses of cis- and trans-2,4,5-triaryl-2-imidazolines and 2,4,5-triarylimidazoles.
