[反应:使用由巴比妥酸盐和2,4,6-三氨基嘧啶H-键合基序组成的自组装体设计了用于邻位烷基化的新的可再循环的负载型催化剂体系。在高温下,该体系是完全均相的,从而提供有效的催化活性,而在室温下,该体系是多相的,形成不溶性固相,以便在反应后容易回收催化剂。
[reaction: see text] 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.
