Abstract

A new recyclable supported catalyst system for orthoalkylation was devised using a self- assembly consisting of the barbiturate and 2, 4, 6-triaminopyrimidine H-bonding motifs. At high temperature, the system is completely homogeneous so as to give an efficient catalytic activity, while it is heterogenized at room temperature to form an insoluble solid phase for the easy recovery of the catalyst after the reaction.
