Abstract
Triorganyltin hydroxides react with catechols in organic solvents in the presence of air oxygen at first to paramagnetic complexes which are investigated by ESR spectroscopy. The reaction has been run using 6 catechols and 5 different organometallic compounds in numerous solvents, so that its general application is proved. The ESR spectra of the solutions show typical hydrogen hyperfine structure and large splittings, which have to be assigned to magnetic coupling of the free electron with 117Sn and 119Sn nuclei. The tin splittings and the g-values significantly depend on the temperature and the solvent. These observations are interpreted in terms of ion pairing effects. A quantitative interpretation is given. The final products of these reactions are diamagnetic compounds which can be isolated in good yields. Based on the elemental analysis, 1H NMR and mass spectroscopy (electron impact, field desorption), the structures are assigned of partly dimerised o-phenylene dioxystannanes.
