The presence of cesium carbonate and tetrabutylammonium iodide (TBAI) facilitated efficient O-alkylation of alcohols with alkyl halides, giving rise to the exclusive formation of mixed alkyl carbonates, The cesium effect was also examined comparatively with other alkali carbonates.

Mild and selective N-alkylation of carbamates was carried out in the presence of cesium carbonate, tetrabutylammonium iodide (TBAI), and a halide. This protocol was highly selective and efficient, offering aliphatic and aromatic N-alkyl carbamates exclusively in high yields.
