Stereochemical nonrigidity of homophenalenyl cations

A strong temperature dependence was observed of chemical shifts in the 13 C NMR spectra of 3b,4- exo -4a,5-tetramethyl-3b,4,4a,5-tetrahydro-4 H -cyclopropa[ a ]phenalen-5-yl cation and its endo -epimer revealing their stereochemical nonrigidity.
