Abstract
In the present study, 5-aryl-3-((E)-3-phenylallylidene)-2(3H)-furanones (3a-f) were synthesized then allowed to react with hydrazine hydrate gave the corresponding hydrazides (4a-c). the reaction of the hydrazides with aromatic aldehydes in refluxing benzene or ethanol gave the corresponding N’-((E) arylidene)-2-(2-oxo-2-arylethyl)-5-phenylpenta-2,4-diene hydrazide (5a-i) or 5 aryl-1-arylidenamino-3-((E)-3-phenylallylidene)-1,3-dihydro-2(3H)-pyrrolone (6a i) respectively. On refluxing the hydrazides in benzene 5-styryl-1,2-dihydro-3 pyrazolones is generated (7a-b). On the other hand, refluxing the hydrazides (4b) in ethanol 1-amino-5-(4-chlorophenyl)-3-(3-phenylallylidene)-1,3-dihydro-2H pyrrol-2-one is produced. The structures of the synthesized compounds were confirmed by spectral data (IR,H1NMR and Mass Spectroscopy).The photophysical properties of furanone derivatives such as UV, Fluorescence, stock shift and quantum yield were studied.
