Notizen:
Rearrangement of the molecular ions of tetracyclone, tetraphenylquinone, tetraphenylthiophene dioxide and pentaphenylcyclopentadienol prior to decomposition, rather than formation of a symmetrical [C4Ar4]+· ion, is considered as an alternative method for the production of [C2Ar2]+·. The p-fluoro substituent is used to elicit information about the positional origins of the [C2Ar2]+· fragments. Operation of a double focusing mass spectrometer in the defocused mode reveals that the integrity of the molecular ion in different systems is affected to varying degrees, ranging from total lack of rearrangement to virtually complete scrambling.
