Silica sulfuric acid-activated poly-1,3-dichloro-5-methyl-5-(4'-vinylphenyl)hydantoin (PDCVH) as an effective reagent for oxidation of 1,3,5-trisubstituted 2-pyrazolines both under microwave irradiation and thermal conditions.
[摘要]：Oxidn. of 1,3,5-trisubstituted 4,5-dihydro-1H-pyrazoles to the corresponding pyrazoles has been achieved by utilizing silica sulfuric acid-activated poly-1,3-dichloro-5-methyl-5(4'-vinylphenyl)hydantoin in EtOH under both microwave irradn. and conventional thermal conditions at room temp. with good yields.
