Abstract
Organosilane cation radicals which have tethered nucleophiles are foun d to undergo rapid intramolecular nucleophilic substitution in both hi gh and low polarity solvents. This reaction competes with both separat ion and return electron transfer within the primary ion radical pair g enerated by photoinduced bimolecular electron transfer. These results demonstrate the ability to effect ion radical substitutions in low pol arity solvents.
