Regioselective synthesis of 1,3,5-trisubstituted pyrazoles

A new and a simple approach toward synthesis of 1,3,5-trisubstituted pyrazoles from chalcone arylhydrazones via oxidative cyclization has been achieved. 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone was successfully used as an oxidizing agent to give excellen

Quenching of Singlet Oxygen by 1,3,5-Triaryl-2-pyrazolines

The efficient quenching of photochemically generated singlet oxygen by four 1,3,5-triaryl-2-pyrazolines (5-8) and p-(diethylamino)benzaldehyde diphenylhydrazone (9) has been investigated by inhibition of the photosensitized oxygenation of 1,3 diphenylisobenzofuran and 2-methyl-2-pentene. 1-Phenyl-3--5--2-pyrazoline (8) quenches singlet oxygen without any reaction at all, and the quenching rate constant reaches a maximum of 5.8 x 109 M-1 s-1.The quenching ability correlates with the value of their one-electron oxidation potentials (Ep).
