Acetylenic ketones. VII—Structural analyses by mass spectrometry of the products obtained from the reaction of acetylenic ketones with nucleophilic sulphur compounds

The mass spectra of β-hydroxy-α-thiobenzoylstyrene derivatives and (E, Z)- or (E, E)-β,β-di(α-aroylstyryl)sulphides as well as β,β′di(α-aroylstyryl)disulphides are discussed. The fragmentation patterns support their proposed structure and configuration.
