Notes:
Characteristic mass spectroscopic data for the identification of ten nitrosophenols is presented. The use of TMS derivatives for gas chromatography-mass spectrometry of 4-nitrosophenols is discussed, together with the use of copper chelates for obtaining direct insertion spectra of 2-nitrosophenols. The fragmentations of nitrosopher ols also show ions derived from their quinonemonoxime tautomers, even under gas chromatography-mass spectrometry conditions, indicating that isomerization occurs in the mass spectrometer. An anomalous elimination of nitrogen from these nitrosophenols has been shown to be a facile reduction of the nitroso moiety which takes place in the ion source of the mass spectrometer.
