Dodecatungstophosphoric acid (H3PW 12O40), samarium and ruthenium (III) chloride catalyzed synthesis of unsaturated 2-phenyl-5(4H)-oxazolone derivatives under solvent-free conditions.
We found that dodecatungstophosphoric acid (H(3)PW(12)O40), 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.
