摘要:
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 beta-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.
