Abstract
When methyliodide and water were added to sodium phenylpropiolthioanilide suspended in ether, C-methylation and C-N bond rupture occurred at the thioamido group. S-[1-Phenyl-2-(thioacetyl) vinyl] isothiuronium p-toluenesulfonate was obtained by adding thiourea and p-toluenesulfonic acid to the ether phase. This salt did not give a free ligand, dithiobenzoylacetone, but produced a zinc chelate, bis (dithiobenzoylacetonato)-Zn (II) by adding aqueous Zn2+ to the aqueous alkaline solution of the salt.
