| Application: | Imidazole can be used as a proton transfer agent in the synthesis of porous organic polymers because of its amphiprotic nature and fast proton transfer behavior. Imidazole can be used as a catalyst in the following • Silylation of alcohols, carboxylic acids, and amines in the presence of silyl chloride in DMF. • To prepare acid chlorides from the corresponding carboxylic acids and phosgene. • Imidazole-PPh3/I2 catalytic system used in the conversion of alcohols into iodides. • Imidazole-PPh3/I2 is used in the diol deoxygenation reaction. |
