Abstract
The transformation of the pyrimidine ring in the reaction of acetonyl anionic σ-complexes of 5-nitropyrimidine and its derivatives with strong base was studied. It is shown that when there is a geminal node at the 4 position, recyclization of the pyrimidine ring to a benzene ring takes place.
