The Ring Opening Reaction of Cyclopolysilanes, (R2Si)n (n=3-6), with Iodine. A Kinetic Study

Article abstract of DOI:10.1246/bcsj.60.769

Reactions of a series of peralkylcyclopolysilanes with iodine were found to proceed via second-order kinetics.Rate constans show that, in general, the smaller rings react faster than larger rings.Values of the activation parameters, E_a and ΔG<*>, decreased with the decreasing ring size and are parallel with those of the oxidation potentials and of the transition energies.
