Reactions of Nitroanisoles. 4.1,2 Reaction of 2,4- and 2,6-DinitroanisoIe with Cyclohexylamine. Evidence of a “Dimer” Nucleophile
The reactions of 2,4- and 2,6-dinitroanisole (DNA) with cyclohexylamine in benzene and in cyclohexane were studied at three temperatures. Two unusual facts were observed: the overall reaction rate is of third order with respect to the amine concentration, and an inverse temperature effect is found f...

| Sumario: | The reactions of 2,4- and 2,6-dinitroanisole (DNA) with cyclohexylamine in benzene and in cyclohexane were studied at three temperatures. Two unusual facts were observed: the overall reaction rate is of third order with respect to the amine concentration, and an inverse temperature effect is found for the reaction of 2,4-DNA in cyclohexane. Both experimental findings and some other “anomalous” results reported in the literature are satisfactorily accommodated in a reaction scheme in which the dimer of the amine is operating. © 1983, American Chemical Society.
