- 44 Downloads
The interaction has been investigated of 1-(4-nitrophenyl)pyrrolin-2-one with aromatic aldehydes in acetic anhydride in the presence of catalytic amounts of pyridine. 1-(4-Nitrophenyl)pyrrolinium perchlorate has been synthesized and was put into a condensation reaction with aromatic aldehydes. As a result 5-arylidene-1-(4-nitrophenyl)pyrrolin-2-onium perchlorates were obtained.
