Abstract:

Cyclic carbonates are valuable as solvents, pharmaceuticalfine chemicals, intermediates for the synthesis of fuel additives and in many biomedical applications. Many catalytic systems have been developed for the synthesis of cyclic carbonates, among these catalysts, salicylaldimine complexes of chromium, cobalt, ruthenium, zinc and aluminum have showed high catalytic activity. [1] However, some of these metals are highly toxic, especially the commonly used cobalt and chromium complexes which limits the potential application of the resulting product species.
