Abstract
The synthesis of O-ethyl thioacetothioacetate
and its zinc(11), cadmium(11), and mercury(11) complexes are described,
together with the zinc(11) and cadmium(11) complexes of ethyl thioaoetoacetate. Infrared, visible, ultraviolet, nuclear
magnetic resonance, and mass spectra have been used to characterize the free
ligand and the new complexes. The free dithio-ligand
is shown to exist in a thioenol form with the thiol
function located at the aceto grouping. The
tetrahedral 1,3-dithio complex, bis(O-ethyl
thioaoetothioacetate)zinc(11) is discussed.
