Organotin derivatives of N-hydroxy-phthalimide and N-hydroxysuccinimide

Abstract

Triorganotin derivatives of N-hydroxyphthalimide and N-hydroxysuccinimide have been obtained by the reaction of bis (triorganotin) oxide and the ligands in 1:2 molar ratio. The molecular weight data indicate the monomeric nature of these compounds. The IR and ¹³C NMR spectral data suggest the absence of coordination from carbonyl group to tin atom. The ¹¹⁹Sn NMR data indicate four coordinated derivatives of these ligands have been obtained by the reactions of organotin moieties and the ligands in 1:1 ratio and they are found to be Polymeric compounds containing Sn-O-Sn bonds. The ¹¹⁹Sn NMR data confirmed the presence of both penta- and hexa-coordinated tin atoms, arising out of intermolecular carbonyl coordination.
