## Abstract The kinetics of the hydride transfer reactions of the dibenzo‐tropylium ion (2) with dimethylphenylsilane (5) and triphenylsilane (6) were used to determine its electrophilicity parameter __E__ = ‐0.71. The nucleophiles 7–9 react 10–40 times faster with 2 than expected from the linear f
