Partial charge silicon

Since our earlier work gave little insight into the nature of the transition state of our proposed mechanism, the work reported in this paper intends to fill that gap. By attaching a phenyl group to the silicon and varying its electronic character with substituents, we can observe the influence of different partial charges on the silicon. This was done for both the alcoholysis and the hydrolysis reactions.
