Notes:
Methyl and picolinyl ester derivatives of isomeric selenalaurates have been characterized by gas chromatography/mass spectrometry. The methyl and picolinyl ester deterivaties give electron impact mass spectra in which ions formed by cleavage at the selenium atom and containing the selenium atom are especially distinctive. The molecular ion (M+) of the methyl ester derivatives was prominent, but not in the case of the picolinyl ester derivatives. Methyl 2-, 3-, 4- and 5-selenalaurate furnished unique mass spectra, which permitted the location of the selenium atom in these isomers. The position of the selenium atom in the 6- to 11-selenalaurate isomers was readily determined from mass spectral results obtained from the picolinyl ester derivatives.
