The combination of a vanadium(V)(salen) complex V+O(salen) EtOSO3- and tetrabutylammonium bromide forms a highly active catalyst system for the reaction between epoxides and isocyanates leading to oxazolidinones. The reaction conditions were optimized and the optimal conditions (80 degrees C in toluene for 5 hours with 2 mol% of vanadium catalyst and 2 mol% of tetrabutylammonium bromide cocatalyst) applied to eight epoxides and six aromatic isocyanates, giving 18 oxazolidinones with conversions of 34-98% and isolated chemical yields of the major regioisomer of 23-89%.
