Large decreases in the oxidation potentials of N-(silylmethyl) aromatic amines (e.g. Me3SiCH2NHPh) could not be correlated with Taft σ* or Hammett σ constants, but a good correlation was obtained with σ+ constants. This is consistent with silylhyperconjugative electron release in the intermediate cation radical.
N-(甲硅烷基甲基)芳香胺(例如Me 3 SiCH 2 NHPh)的氧化电位的大幅下降与Taftσ *或Hammettσ常数无关,但与σ +常数具有良好的相关性。这与中间阳离子自由基中甲硅烷基超共轭电子的释放是一致的。
