The general fragmentation patterns of five selected title compounds are described. The most significant mass spectral features arise from the interaction of aryl substituents with the adjacent heterocyclic ring. The decomposition of the compounds bearing an ortho nitro group in the S-aryl moieties is strongly affected by a prominent “ortho effect”.
