The thermal and photochemical reactions of organotin compounds with the 2-amino-4-tert-butylphenol have been studied by ESR and other spectroscopic methods at room temperature. The free radical complex generated from the ground-state reaction of the aminophenol with hexaphenylditin is very stable and shows a characteristic ESR with 15 hyperfine lines and tin satellite hyperfine splittings. The complex has been characterized by UV-visible and near-IR absorption spectroscopies. Tin is probably coordinated in this radical complex to the oxygen and nitrogen of the aminophenol. Hexamethylditin and tri-tert-butyl tin hydride also produce similar radical complexes.
