%X The new monothio-&#946;-diketone l,l,l-trifluoro-4-mercapto-4-(2'-naphthyl)but-3-en-2-one, &#946;C10H7- C(SH)=CHCOCF3, and its chelates with iron(111), ruthenium(111), cobalt(111), rhodium(111, nickel(11), palladium(11), platinum(11) and zinc(11) have been prepared. The mass spectrum of the monothio-&#946;-diketone displays considerably more peaks than that of its parent &#946;-diketone. Both spectra give peaks for the ion CllH7+ (RC+ ; R = &#946;-C10H7). The mass spectra of the metal chelates show some differences determined by the metal. All the metal chelates except that of zinc show peaks due to the ion M'-MetS and its daughter ions (M' = M for MetL2 and M - L for MetL3 ; L = &#946;-C10H7C(S)=CHCOCF3). It is considered that the &#946;-naphthyl group affects the fragmentation pattern, since the mass spectra differ considerably from those of metal chelates of other monothio-&#946;-diketones.
