RISA novel approach to synthesis of new imidazo[2',1':2,3]thiazolo[5,4-d]pyrimidines as a class of heterocyclic compounds
we have presented an efficient synthetic pathway for the synthesis of new derivatives of imidazo[2ˈ,1ˈ:2,3] thiazolo[5,4-d]pyrimidin 4(a-g) via the heterocyclization of 2,5-dichloro-7-methylthiazolo[5,4-d]pyrimidine (1) ...
A novel synthesis of imidazo[1,2-c]pyrimidines
A new method for the preparation of imidazo[1,2- c ]pyrimidines is described.
Organic inorganic hybrids of imidazole complexes of zinc (II) for catalysts in the glycerolysis of urea
Theoretical study on ionic liquids based on DBUH + : Molecular engineering and hydrogen bond evaluation
the ion pairs of
DBUH+ based ILs, including 10 functionalized imidazole anions were investigated.
For this purpose, the electrostatic potential surfaces were analyzed to detect the
most probable interaction sites of DBUH+. On the basis...
Structure of 2,4,5-triphenyl-1H-Imidazole and the substitution effect of F, Cl, and OH groups in para position of 2-Ph ring; A DFT study
Over the century, imidazoles have received significant attention due to their reactions and biochemical properties. Even today, research in
imidazole chemistry continues. Several substituted imidazoles are known as inhibitors of P38 kinase...
DFT Study on CO2 Absorption by a New Generation of Ionic Liquids
consisting of DBU as a cation and four different imidazole derivatives
as the anions. The results showed that the bond length of the N-C decreases at the transition state,
showing that CO2 is absorbed by the ILs. Natural bond orbital (NBO...
A novel imidazolium-based acidic ionic liquid as an efficient and reusable catalyst for the synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazoles
A novel acidic ionic liquid based on imidazoliumcation is designed, synthesized, and successfully used as a catalyst for the one-pot synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazole derivatives. The remarkable feature of this new catalyst is its...
Deep eutectic solvent for multi-component reactions:a highly efficient and reusable acidic catalystfor synthesis of 2,4,5-triaryl-1H-imidazoles
Efficient synthesis of 2,4,5-trisubstituted imidazoles has been achieved by three-component cyclocondensation of benzil or benzoin, an aldehyde, and ammonium acetate by use of an acidic catalyst. The catalyst is a deep eutectic mixture of choline...
Synthesis of 2,4,5-triaryl-1H-imidazoles using a potent, green and reusable nano catalyst (FHS/SiO2)
A simple, green and efficient method for synthesis of 2,4,5-trisubstituted imidazoles is described via three-component cyclocondensation of benzil or benzoin, aldehyde and ammonium acetate by using the nano SiO2-supported ferric hydrogen sulfate...
