The silica supported H3PW12O40 (a heteropoly acid) as an efficient and reusable catalyst for a one-pot synthesis of β-acetamido ketones by Dakin-West reaction

Heteropoly acid H3PW12O40 (PW) supported on silica (PW/SiO2) as an efficient, reusable solid acid catalyst have been studied in the one-pot, four-component coupling process for the synthesis of β-acetamido ketones.
