The monomer-dimer equilibria of 2,6- and 3,5-dimethylnitrosobenzenes in CDCl3 solution were investigated by 1H and/or 13C NMR spectroscopy.The mixed systems nitrosobenzene + 2,6-dimethylnitrosobenzene and 2,6-dimethylnitrosobenzene + 3,5-dimethylnitrosobenzene were also studied, and mixed azodioxy dimers were identified.In all systems exchange occurs exclusively between dimer and monomer species, rates and activation energies being calculated from time-dependent 1H 1D spectra and/or 1H 2D-EXSY spectra measured at different temperatures.
