Hydrogencarbon, carboncarbon double rearrangement induced by proximity effect in alkyldiaryl- and triarylmethyl cations | ||

ABSTRACT: | ||
The double rearrangement process affording benzyl (or tropylium) ions, which constitutes the main fragmentation reaction for 2-alkylheterodiphenylmethyl cations, is also observed in the presence of a further substituent (alkyl or aryl) linked to the benzylic carbon. This process is still responsible for important peaks in the mass spectra. | ||
Keywords: mass spectrometry, double rearrangement, alkyldiaryl cation, triarylmethyl cation, deuterium labelling, proximity effect. |
