Layered zirconium hydrogen phosphate, exfoliated by intercalation of propylamine and then exchanged with alkali metal ions has proved to be an excellent catalyst for Michael addition of 13-dicarbonyl compounds. The reactions occur with high yield, in mild conditions and with ease of work up. The catalyst, recovered from the reaction vessel, may be reused several times.

Abstract
Layered zirconium hydrogen phosphate, exfoliated by intercalation of propylamine and then exchanged with alkali metal ions has proved to be an excellent catalyst for Michael addition of 13-dicarbonyl compounds. The reactions occur with high yield, in mild conditions and with ease of work up. The catalyst, recovered from the reaction vessel, may be reused several times.File in questo prodotto:
