AbstractThe mass spectra of a series of substituted butenolides were studied. Their fragmentations in the mass spectrometer strongly depend upon the nature of the substitutents. The fragment's ions include the lactone skeletons, substituents, and resultant derived from the loss of a carbon dioxide from lactone.
