Pyridazinones are organic compounds that are commonly found in drugs, pesticides, and natural products with biological
activity. To date, a considerable number of synthetic routes to obtain pyridazinones have been published although only
a few have described efficient pathways to prepare N-arylated pyridazinones. In contrast to methods found in literature in
which strong reaction conditions or metallic catalysts are employed, this study proposes a new route to obtain N-arylated
pyridazinones using aryldiazonium salts and furan derivatives in mild reaction conditions with water as the solvent. Diazonium
salts are highly reactive compounds and so their use results in an important gain in terms of the efficiency of the process. The
reaction mechanism is elucidated by DFT calculations and confirmed by empirical test
