The reactivity of di- and triphenyltin(IV) hydroxamate complexes of composition (C6H5)2SnCl2-n(XBHA)n and (C6H5)3Sn(XBHA) (n = 1 and 2; X = p-OMe, o-Cl, p-NO2; BHA = anion of XArCONHOK) with ligands containing labile protons such as acetylacetone (acacH), dibenzoylmethane (dbmH), salicylaldehyde (salH) and o-chlorophenol and thiophenol has been studied to investigate the preferential attack on Sn-C, Sn-Cl or Sn-O bond. The title complexes do not react with the chelating ligands. However, the reactions of (C6H5)2SnCl(XBHA) with sodium salt of the chelating ligands NaL (L= acac, dbm and sal) readily proceed to yield the mixed ligand complexes of composition (C6H5)2Sn(XBHA)*L, while the treatment of (C6H5)2Sn(XBHA)2 and (C6H5)3Sn(XBHA) with phenols results in the complete displacement of the hydroxamate group with the phenolate ion.
