Dynamic PMR spectroscopy was used to detect the degenerate rearrangement of 5-nitro-1,2,3,4,5-pentamethyl-1,3-cyclopentadiene. The rate of the 1,2 shift of the nitro group is virtually the same in solvents of different polarity. A linear correlation was found between the activation free energies of the 1,2 shift of the nitro and methyl group encompassing the degenerate rearrangements of 5-R-1,2,3,4,5-pentamethyl-1,3-cyclopentadienes and arenonium ions.
