Synthesis of monothiohydroxamic ligands and their lead complexes. Structures of N-methyl-3-pyridothiohydroxamic acid, bis(N-methyl-3-pyridothiohydroxamato) lead(II) and bis(N-cyclohexyl-phenylacetothiohydroxamato) lead(II)

dithiophenylacetate with several substituted hydroxylamines in aqueous solution at neutral pH gives good yields of the resultant thiohydroxamic acids. The lead coordination chemistry of these compounds is being investigated as part of a program to develop lead-specific sequestering agents. The single crystal structure of bis(N-cyclohexyl-phenylacetothiohydroxamato) lead(II) shows that it is essentially

N-alkyl-O-acyl thiohydroxamic acid derivatives were prepared in good yields by the treatment of their parent hydroxamic acids with Lawesson's reagent. Some of these thiohydroxamic acid derivatives exhibit the ability to undergo rearrangement under basic conditions possibly via [3,3]-sigmatropic in moderate to good yields similar to their parent hydroxamic acids.
