Reactions of nitroanisoles. Part 6. Reaction of 2,6-dinitroanisole with cyclohexylamine in mixed solvents. Solvent evidence for the 'dimer' mechanism
The reaction of 2,6-dinitroanisole with cyclohexylamine in methanol and benzene-methanol was studied at several amine concentrations. Although the reaction rate in methanol is higher than in benzene, addition of small amounts of methanol to the benzene solution diminishes the rate of reaction (which...
