• ESR Studies of Phenoxyl Radicals Produced by the PbO₂Oxidation of Hindered Polyphenols. III.<i>p</i>- and<i>m</i>-Phenylenebisgalvinoxyls, Stable Triplets
  作者：Kazuo Mukai

  DOI：10.1246/bcsj.48.2405

  日期：1975.9

  PbO2 oxidation of two hindered polyphenols produced, in turn, primary, secondary, and ternary radicals. The ternary radicals are π-conjugated biradicals; the structures of the radicals were assigned to be p- and m-phenylenebisgalvinoxyls. Both zero field splitting parameters and hyperfine splitting constants were determined from ESR spectra.

  两种受阻多酚在二氧化铅的氧化作用下依次产生了一级自由基、二级自由基和三元自由基。三元自由基是π共轭双自由基；自由基的结构被认为是对和间苯双乙烯基。根据 ESR 光谱测定了零场分裂参数和超细分裂常数。
