Abstract: We found that dodecatungstophosphoric acid (H3PW12O40), samarium and ruthenium(III) chloride act as efficient catalysts for synthesis of unsaturated 2-phenyl-5(4H)oxazolone derivatives under solvent-free conditions. The key features of the reported protocols are short reaction times, high yields of products, ambient conditions and simple workup.
