Later Olah et al. showed that the trans-chloride 605 with SbFj—SO Fl yield a 3-cyclohexenyl cation 606, but not the ion 520 thus, just as under solvolytk conditions, ion 520 is formed only when cr-participation is possible in the transition state of ionisation. In the same paper it was pointed out that ion 520 could be generated from the alcohol if freshly distilled SbFj in SOjFQ (—78 "C) was used the admixtures of proton acids, the authors maintain, favour the opening of the cyclopropane ring before ionization. The ionization of 3-methyl- 607 and 3-phenyl-cis-bicyclo[3,l,0]hexanol-3 608 in SbFj—SOjFCl results in the 3-methyl-cyclo-hexenyl ion 609 and the 3-methyl-l-phenylcyclopentenyl ion 610. That the ionization of tertiary substrates results in classical tertiary carbocations rather than trishomocyclopropenyl ions appears to be due to the hindrance in passing from the conformation of the bath to the chair which is indispensable for the formation of a delocalized ion.
