Study On Organic Reactions Catalyzed By Acidic Ionic Liquids

This thesis divides into two aspects. In this paper, we describe the study on synthesis of N-(α-alkoxyalkyl)benzotriazole derivatives and synthesis of bis(indolyl)nitroethane bis(indolyl)nitroethane catalyzed by acidic ionic liquids.Firstly, we discussed the study on synthesis of N-(α-alkoxyalkyl)benzotriazole derivatives catalyzed by acidic ionic liquids, the selection of these reactions conditions was investigated and the optimum experimental conditions were found. The synthesis of N-(α-alkoxyalkyl)benzotriazole derivatives was catalyzed by acidic ionic liquids [hmim]HSO4 at the amount of 20 mol% under solvent-free conditions.Secondly, we study the synthesis of bis(indolyl)nitroethane derivatives catalyzed by acidic ionic liquids. The different ionic liquids, the mount of catalyst and the reuse of the acidic ionic liquid [hmim]HSO4 were discussed. The results showed that [hmim]HSO4 was good catalyst for the synthesis of bis(indolyl)nitroethane derivatives and it was the best when the amount of [hmim]HSO4 was 20 mol%.
