【 摘 要 】

We have found that dodecatungstophosphoric acid (H₃PW₁₂O₄₀), samarium or ruthenium(ΙΙΙ) chloride act as efficient catalysts for the 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 under ambient conditions and simple workups.
