CARBONYLDIIMIDAZOLE

The molecular formula for Carbonyldiimidazole is (C 3 H 3 N 2) 2 CO. It can be prepared with the reaction of phosgene and four equivalents of imidazole under anhydrous conditions. The results are a 90% yield after removing solvent and imidazolium cholride... Carbonyldiimidazole a organic compound used primary as a reagent in organic synthesis and for coupling of amino acids for peptide synthesis. CDI is a white crystalline solid. Mainly used to convert amines into amides, carbamates, ureas. Conversion of alcohols into ester can also be done... Carbonyldiimidazole hydrolyzes giving back imidazole. You can determine the purity by the amount of CO 2. (C3H3N2)2CO + H2O → 2 C3H4N2 + CO2
