4,4 '-(Trimethylene)bis(2,6-di-t-butylphenoxy) diradical: An application of the sequential redox-solid state photolysis (SRSSP) method

The oxidation of 4,4'-(trimethylene)bis(2,6-di-t-butylphenol) with lead dioxide underwent intramolecular cyclization at the 4,4'-positions to give a dispiro-compound. Irradiation of the dispiro-compound in a methylcyclohexane matrix at -150 degrees C produced 4,4'-(trimethylene)bis(2,...

Summary:The oxidation of 4,4'-(trimethylene)bis(2,6-di-t-butylphenol) with lead dioxide underwent intramolecular cyclization at the 4,4'-positions to give a dispiro-compound. Irradiation of the dispiro-compound in a methylcyclohexane matrix at -150 degrees C produced 4,4'-(trimethylene)bis(2,6-di-t-butylpheoxy) diradical which has a stable triplet state.
