Abstract Products of the reaction between the three fluorinated nitrobenzenes (2,3,4,6-tetrafluoronitrobenzene, 2,3,4,5-tetrafluoronitrobenzene, pentafluoronitrobenzene) and tetramethylguanidine in acetonitrile were isolated and identified by analytical and spectroscopic methods. As the result of these reactions, ortho and para substituted isomers were formed. In two of the reactions, the para isomers were the main products. The kinetics and the mechanism of these reactions are discussed.
