摘要：
A theoretical study of the structures of a series of 5-substituted-6-phenyl-3(2H)-pyridazinones has been carried out using quantum-mechanical calculations. This study indicates a significant effect of the nature of the substituent at the 5-position on the reactivity of this system. The results have also been confirmed by means of H-1 NMR measurements. The outcome of this work has guided the development of novel and efficient synthetic pathways to obtain pharmacologically useful 6-phenyl-4,5-substituted-3(2H)-pyridazinones.
