Studies in mass spectrometry. Part V. Mass spectra of benzoquinones
Abstract
The mass spectra of fifteen benzoquinones, variously substituted with methyl, hydroxyl, and methoxyl groups, are reported and discussed. The fragmentation patterns, which have been investigated in a number of cases by exact mass measurements and deuterium labelling, can be usefully correlated with the type of substituent and the nature of the substitution pattern.
