Abstract

Abstract The scope of homogeneous Lewis acid-catalyzed benzo [N, N]-heterocyclic condensation was expanded to include the use of various metal salts not reported in the literature and was finally selected. Among various solid supports activated with, heterogeneous proved to be the most effective and significantly higher conversions were achieved compared to itself. The results of TG-DTA and BET indicated that dispersed ...
