ABSTRACT:
There is provided an efficient single step process to produce 4-aryl-2-perfluoroalkyl-3-oxazolin-5-one from arylglycine and a perfluoroacylating agent in the presence of a phosphorous trihalide and a solvent.
The oxazolinone is a key intermediate in the production of insecticidal, nematicidal and acaricidal arylpyrrole compounds.
