Abstract

The combination of Ph 4 SbI and Bu 3 SnI proved to be a new excellent catalyst for effecting cycloaddition reaction of inactive 2, 3-disubstituted oxiranes with isocyanates under neutral conditions, yielding oxazolidinones in high yields, while either of both metal iodides had no activity individually.
