Abstract
Layered zirconium hydrogen phosphate, exfoliated by intercalation of p ropylamine and then exchanged with alkali metal ions has proved to be an excellent catalyst for Michael addition of beta-dicarbonyl compound s. The reactions occur with high yield, in mild conditions and with ea se of work up. The catalyst, recovered from the reaction vessel, may b e reused several times.
