    Noteworthy Chemistry - American Chemical Society

    American Chemical Society: Chemistry for Life. Water is an excellent solvent for imidazole carbonylation. Urea and carbamate are important structures in organic synthesis and medicinal chemistry. Abstract. The reactions of non-benzylic primary and secondary aliphatic alcohols with carbonyldiimidazole (CDI) afford the corresponding carbamates but not N-alkylimidazoles.For benzylic primary alcohols, formation of N-alkylimidazoles proceeds reasonably at 170 °C in several different solvents and occurs by way of the initially formed carbamate.. However, under these rather forcing ...
