Abstract :A polyinsert ignore into journalissuearticles values(4-vinylpyridine);-supported Brønsted ionic liquid was easily prepared from its starting materials and used as a novel, highly efficient, and reusable heterogeneous catalytic system for the synthesis of 4,4`-insert ignore into journalissuearticles values(arylmethylene);bisinsert ignore into journalissuearticles values(3-methyl-1-phenyl-1H-pyrazol-5-ols); from the condensation reaction between aromatic aldehydes and 2 equivalents of 3-methyl-l-phenyl-5-pyrazolone.
Keywords : 3 Methyl l phenyl 5 pyrazolone, aldehydes, ionic liquid, one pot synthesis, heterogeneous catalysis
