A series of novel 5-Aryl-3-(3-coumarinyl)-1-benzothiazolyl-2-pyrazolines have been synthesized by the reaction of 3-coumarinyl chalcones with 2-hydrazinobenzothiazole in hot ethanol. And the structures of these new compounds have been characterized by 1HNMR, MS and elemental analysis. The fluorescence spectra of these compounds were also measured. All the compounds showed up strong green light emissions (λem: 557-570nm). The results showed that the absorption maxima of the compound vary from 415 to 420nm depending on the group bonded to pyrazolines rings.

A series of coumarin-chalcone hybrid compounds and coumarins linked to pyrazoline was synthesized in good yield and short time using a simple and efficient method. This method involved the one-pot reaction of salicylaldehyde, an α-ketoester and an aromatic aldehyde (in the case of the coumarin-chalcone derivatives) in addition to hydrazine hydrate (in the case of the pyrazolyl coumarins) in the presence of a catalytic amount of bismuth triflate [Bi(OTf)3, 5 mol%]. The synthesized compounds showed scavenging activity towards the free radical 2,2-diphenyl-1-picrylhydrazyl. All compounds were characterized using IR, 1H NMR and 13C NMR spectroscopy.
