Immobilized sulfonic acid functionalized ionic liquid on magnetic cellulose as a novel catalyst for the synthesis of triazolo[4,3-a]pyrimidines
The Brønsted acidic ionic liquid 1-(propyl-3-sulfonate) vinyl imidazolium hydrogen sulfate [IL] was supported on modified magnetic cellulose. The physical structure, composition, and functional groups of the novel supported ionic liquid catalyst were characterized via XRD, FT-IR, EDS, SEM, VSM, TGA,...

| description | The Brønsted acidic ionic liquid 1-(propyl-3-sulfonate) vinyl imidazolium hydrogen sulfate [IL] was supported on modified magnetic cellulose. The physical structure, composition, and functional groups of the novel supported ionic liquid catalyst were characterized via XRD, FT-IR, EDS, SEM, VSM, TGA, TEM, and BET techniques. Owing to the combination of nano-support features and flexible imidazolium linkers, it acted as a “quasi-homogeneous” catalyst to catalyze the preparation of triazolo[4,3-a]pyrimidine derivatives by a one-pot three-component reaction of active methylene compounds (ethyl cyanoacetate or malononitrile), aminotriazole and aryl aldehydes. The catalyst shows good catalytic activity for the synthesis of triazolo pyrimidines after six times of recycling. |
