Phosphomolybdic Acid, also called Molybdophosphoric Acid, is a yellow crystalline solid of very high solubility in water and several oxygenated solvents. There are a number of salts of the phosphomolybdic acid. This heteropoly acid is tribasic and has a tendency to undergo some hydrolytic degradation. NMR evidence has shown that the three protons in the heteropoly anion are present as H30+ ions.
A simple and one-pot method for the synthesis of dihydropyrimidones is reported. 12-molybdophosphoric acid in refluxing acetic acid catalyzes this three-component condensation reaction to afford the corresponding pyrimidinones in good yields.
