Summary
The reactions of β-diketones and β-ketoaldehydes with hydrazine-S-methyl carbodithioate, hydth, have been studied in the absence and presence of metal(II) ions. A series of dimeric monoligand chelates [Ni(β-dikhydth-2H)]2 have been isolated. The reaction of these chelates with monodentate Lewis bases yields square planar [Ni(β-dikhydth2H)B] chelates. Bisligand chelates of benzoylacetone monohydrazones [M(Bzachydth-H)2] (M=Cu or Zn) have been also synthesized, as have a series of NiII and ZnII chelates of β-diketone bishydrazones of the type [M(β-dik(hydth)2-2H)].
