Preysslerʹʹs anion, [NaP5W30O110]14-, as an efficient catalyst for the selective synthesis of geminal diacetates

The highly selective catalytic synthesis of gem-bis (acyloxy)–alkanes has been studied using Preyssler catalyst, H14[NaP5W30O110] at room temperature and under solventless conditions. Comparison of Preyssler catalyst with the other heteropoly anions showed that, in all cases, maximum of product yields was observed by using H14[NaP5W30O110] as catalyst. The effects of catalyst moles and time of reaction were studied.
