An attempt has been made to correlate the rate constants of substituted acetals with the chemical shift of the benzylic proton of the acetals (log k₂ vs δ). This correlation is similar to that of which is obtained betneen σ vs δ. The benzylic proton chemical shift in acetals is found to be the characteristics of acetals. The benzylic proton docs not couple with other protons and hence appears as a singlet, which would ensure effective correlation.
