The reactions of carbon dioxide (CO2) with 1-phenylaziridine (1) to afford 3-phenyl-2-oxazolidone (2) were carried out in the presence of organo-antimony and -tin compounds as catalysts.Tetraphenylstibonium bromide (Ph4SbBr) and triphenyltin bromide (Ph3SnBr) were found to be active catalysts.The use of a polar aprotic solvent, such as a HMPA, provided optimal reaction conditions.
