Abstract
The reaction between polystyrene 3-formylsalicylate and 2-Aminobenzylalcohol in DMF in the presence of ethyl acetate results in the formation of polystyrene N-(2-hydroxymethylphenyl)-2′-hydroxybenzylideneimine-3’carboxylate (I). A benzene suspension of I reacts with mercaptoacetic acid undergoes cyclization and forms polystyrene N-(2-hydroxymethylphenyl)-C-(3′-carboxy-2′-hydroxyphenyl)thiazolidine-4-one, PSCH2–LH2 (II). A DMF suspension of II reacts with Mn(II) and Cd(II) ions and forms the corresponding polystyrene-anchored coordination compounds, [PSCH2–LHMn(OAc)(DMF)3] (III) and [PSCH2–LHCd(OAc)(DMF)] (IV). The polystyrene-anchored coordination compounds have been characterized on the basis of elemental analyses, spectral (IR, reflectance) studies and magnetic susceptibility measurements. II behave as a monobasic bidentate OS donor ligand in the coordination compounds. An octahedral structure for III and tetrahedral structure for IV are suggested.
