Notes:
The IR spectra of isomeric bicyclobutonium (1), delocalized cyclopropylcarbinyl (2) and 1-methylally (3) cations were recorded at 180 K in SbF5 matrices. Cations 1 and 2 generated from cyclopropylcarbinyl and cyclobutyl chloride, respectively, rearrange to 3 at temperatures above 230 K. The structures 1, 2 and 3 were confirmed by comparison of the recorded frequencies with the MP2/6-31G*-calculated values. These results are in accord with prediction that ions 1 and 2 are rapidly equilibrating non-classical structures.
