The solvolysis rates of 2-(aryldimethylsilyl)ethyl chlorides 3 were measured using a conductometric method.The analysis of the Yukawa-Tsuno LArSR equation gives a reaction constant of ρ=-1.42 and a high resonance demand of r=1.48.This result indicates that the β-silicon effect is attributed to the cyclic transition state structure with a positive charge on the silicon in this primary system.
