[ 1 ] - Efficient synthesis of xanthene derivatives in aqueous media in the presence of Cu-anchored furfural imine-functionalized halloysite
A novel hybrid catalyst based on grafting Cu on furfural imine-functionalized halloysite was designed, characterized and used for promoting synthesis of xanthene derivatives via three- component reaction of benzaldehyde derivatives, dimedone, and β-naphthol in aqueous media and under mild reaction condition. The results established high catalytic activity of the hybrid system, which was superio...
[ 2 ] - An efficient synthesis of imidazo[1,2-a]azine using nanocrystalline alumina powder
Nanocrystalline alumina powder has been synthesized using solution combustion method. The obtained nanocrystalline alumina powder was used as an efficient catalyst for the synthesis of imidazo[1,2-a]azine derivatives from one-pot three component reaction of benzaldehyde, 2-aminoazine and trimethylsilylcyanide under ultrasonic irradiation and refluxing condition. Reusability of catalyst and shor...

[ 5 ] - فسفومولیبدیک اسید نهش یافته بر روی سطح هالویسیت عاملدار شده با مایع یونی: کاربرد کاتالیستی برای سنتز پیرازولوپیرانوپیریمیدین ها
هتروپلی اسیدها کاتالیست های دوعاملی می باشند که می توانند هم واکنش های اسید ـ کاتالیست و هم واکنش های اکسایشی را کاتالیز کنند. این کاتالیست ها غیر سمی بوده و پایداری گرمایی به نسبت بالایی دارند. با این حال انحلال زیاد این مواد در آب و بسیاری از حلال های آلی باعث محدود شدن کاربرد آن ها شده است.در این پژوهش برای رفع این مشکل و تولید کاتالیستی ناهمگون، از کلی هالویسیت به عنوان پایه کات...
