It has now been found that trichloroacetyl chloride is capable to react with Schiff bases in the presence of triphenylphosphine to give 3, 3-dichloro-2-azetidinones. Mechanistically the reaction appears to involve the chlorine cation extraction from the initially formed adduct by triphenylphosphine.
