Abstract
The kinetics of degenerate pendular rearrangement of 3b,exo-4,4a,5-tetramethyl-3b,4,4a,5-tetrahydro-4H-cyclopropa[a]phenalen-5-yl cation and its endo epimer, generated under conditions ensuring their long life, were studied by dynamic NMR spectroscopy. The rearrangement mechanism is discussed with account taken of the results of quantum-chemical calculations and published data for related rearrangements.
