Thio derivatives of β-diketones and their metal chelates. XVI. Nickel(II), palladium(II), platinum(II), zinc(II) and cobalt(III) chelates of some new fluorinated Monothio-β-diketones

Abstract

The new fluorinated β-diketones RCOCH₂COCF₃ (R = p-ClC₆H₄, m-ClC₆H₄, m-BrC₆H₄, m-MeC₆H₄ and m,p-C1,C₆H₃) have been prepared. The monothio-β-diketones RC(SH)=CHCOCF₃ derived from these β-diketones were also prepared. Complexes of these monothio-β-diketones and of p-FC₆H₄C(SH)=CHCOCF₃ with nickel(11), palladium(11), platinum(11), zinc(11) and coba1t(111) have been prepared and characterized. All the complexes are stable and display sharp melting points.
