Conclusions
-
1.
For tin-containing complexes of 3,6-di-tert-butyl-o-benzoquinone, the parameters of the ESR spectra (HFI with ring protons and with117Sn and119Sn nuclei) and the distribution of spin density in the free-radical ligand depend on the nature of the substituents on the Sn atom.
-
2.
The frequency of “stannotropic” migration in the radicals that we have investigated is determined by the strength of the Sn-O bond, the coordination unsaturation of the Sn atom, and the spin density on the univalent O atom; as these latter factors become more important, pentacoordinated structures appear, with equivalent Sn-O bonds.
-
3.
The polarity of the medium determines the direction of the reaction of ligand substitution in the interaction of the o-quinone with organic monochlorotin compounds; in nonpolar media, the organic ligand is replaced, and in polar media (DMSO), the Cl atom is replaced.
