In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of 2,4,5-triaryl-1H-imidazole derivatives using SiO2-NaHSO4, published in 2020, which mentions a compound: 484-47-9, Name is 2,4,5-Triphenylimidazole, Molecular C21H16N2, COA of Formula: C21H16N2.
A mixture of benzyl, aromatic aldehydes and ammonium acetate in presence of SiO2-NaHSO4 under solvent-free condition converted to 2,4,5-triaryl-1H-imidazoles. The short reaction time, cleaner reaction and easy workup make this protocol practical and economically attractive.
《Synthesis of 2,4,5-triaryl-1H-imidazole derivatives using SiO2-NaHSO4》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(2,4,5-Triphenylimidazole)COA of Formula: C21H16N2.
