Vm. Karpov et al., 4-MEMBERED RING-CLEAVAGE OF PERFLUORINATED BENZOCYCLOBUTENE AND 1-METHYLBENZOCYCLOBUTENE UNDER THE ACTION OF I-2-SBF5, Mendeleev communications, (2), 1997, pp. 71-72
Interaction of perfluorobenzocyclobutene with I-2 In an SbF5 medium le
ads to the formation of 2-iodoperfluoroethylbenzene and perfluoro-o-xy
lene; perfluoro-1-methylbenzocyclobutene in the I-2-SbF5 system is tra
nsformed into perfluoro-2-ethyltoluene.
