Ma, Xue-lin published the artcileCondensation reaction of aromatic aldehydes and 1-phenyi-3-methyl-4-benzoyl-pyrazolone catalysted by phosphotungstic acid loaded on 404 organic support<\/i><\/b>, Name: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one<\/a>, the publication is Huaxue Shiji (2014), 36(7), 646-650, database is CAplus.<\/p>\n

Many loaded-catalysts are applied to the Mannich reaction, but they have disadvantages such as low yield, unstability of loaded rate and asking for long time. 404 Organic support loaded phosphotungstic acid was synthesized by the reaction of 404 organic support and phosphotungstic acid in CC14. The effects of different reaction conditions on the yields were investigated. The condensation reaction of aromatic aldehydes and 1-phenyl-3-methyl-4-benzoyl-pyrazolone was catalyzed by 404 organic support loaded phosphotungstic acid. Simultaneously the products were determined by IR, 1<\/sup>HNMR and elemental anal. The catalyst was provided with stable cubic crystal spatial structure and good dispersion. This protocol has advantages of stability of loaded rate, short time, mild condition, high yield, high selectivity, simple work-up, environmental friendly procedure and the catalyst can be reused.<\/p>\n
