New Diels-Alder reactions of tropylium ion are studied, and the observed stereoselectivities suggest that solvent effects determine the steric course of these reactions. Troplylium ion (1) has been found to undergo a number of Diels-Alder type reactions with high endo selectivity.2
## 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
