A series of 1,3,5-trisubstituted pyrazolines were highly efficiently oxidized to corresponding pyrazoles with nitric oxide at room temperature in CH2Cl2. The structure of products was characterized by various spectroscopic data. This entry offers several advantages like simple handlings, mild reaction conditions and high yields of products.

Key words: oxidative aromatization, nitric oxide, pyrazoline, pyrazole
