A ß-cyclodextrin-SO3H carbon based solid acid catalyst was prepared in convenient and ecofriendly manner. The synthesized samples were characterized by FTIR, PXRD, EDAX and NH3TPD to illustrate that the carbon material has been functionalized with -SO3H, -COOH and -OH groups. The catalytic performance of prepared material was studied for synthesis of quinoxaline derivatives from reaction of 1,2-diamines and 1,2-diketones. The results showed excellent yield. The main advantage of this methodology is an easy catalyst preparation and separation, moderate reaction conditions, excellent catalyst recyclability and high product yields. |
