Abstract:
According to the NMR data, protonation of 5,5,10,10-tetramethyl-5,10-dihydroindeno[2,1-a]indene in the system HSO3F-SO2ClF-CD2Cl2 at -80degreesC gives rise to long-lived 5,5,10,10-tetramethyl-2H-5,10-dihydroindeno[2,1-a]indenium ion which undergoes isomerization into 4b,5,10,10-tetramethyl-4b,5,9b,10-tetrahydroindeno[2,1-a]inden-5-yl cation on raising the temperature. On the basis of the data obtained for rearrangements of such carbocations an alternative mechanism has been proposed for the rearrangements of structurally related carbocations having a bicyclo[3.3.0]octane skeleton.
