les cyclopropylcarbinols dérivés de la thujone peuvent subir trois clivages distincts: le clivage exo, le clivage endo et l'intéressant réarrangement cyclopropylcarbinyle.
thujone-derived cyclopropylcarbinols can cleave via three distinct pathways: the exo cleavage, the endo cleavage, and the interesting cyclopropylcarbinyl rearrangement.

on a effectué les acétolyses des composés suivants: les chloromethyl-7 et bromomethyl-7 dibenzobicyclo[2.2.2]octatriènes, les chloro-8 et bromo-8 méthylène-7 dibenzobicyclo[2.2.2]octatriènes-2,5, le bromo-4 méthylène-8 dibenzobicyclo[3.2.1]octadiène-2,6 et le chloro-2 dibenzotricyclo[3.2.2.02,4]nonadiène. les résultats observés sont en accord avec un mécanisme impliquant la présence de deux carbocations qui s'interconvertissent par une transposition de wagner–meerwein et l'absence du cation dibenzosemibullvalénylcarbinyle-1 qui est l'isomère cyclopropylcarbinyle de l'un des cations produits.
acetolyses of 7-chloromethyl- and 7-bromomethyldibenzobicyclo[2.2.2]octatrienes, 8-chloro- and 8-bromo-7-methylenedibenzobicyclo[2.2.2]octa-2,5-dienes, 4-bromo-8-methylenedibenzobicyclo[3.2.1]octa-2,6-diene, and 2-chlorodibenzotricyclo[3.2.2.02,4]nonadiene were carried out. the results observed were consistent with the involvement of two carbocations interconverting by a wagner–meerwein rearrangement, and with the absence of the 1-dibenzosemibullvalenylcarbinyl cation, which is the cyclopropylcarbinyl isomer of one of the cations produced.
