The rate data for the Menschutkin reaction between strongly activated Z-substituted benzyl ptoluenesulfonates and Y-substituted N,N-dimethylanilines in acetonitrile at 35 ยฐC fit the equation, , which is consistent with concurrent first-and second-order processes. The k 1 and k 2 values for each sub
