Transition-state structures for the carbocation nucleophile combination reactions of (4- substituted-4'-methoxydiphenyl) methyl cations with water, chloride, and bromide ions in acetonitrile water mixtures have been investigated by measuring the secondary α-deuterium kinetic and equilibrium isotope effects. Rate constants in the combination direction were measured with laser flash photolysis. Equilibrium constants were measured for the water ...
