DeTar, DeLos F. published the artcileCalculations of steric hindrance in ester hydrolysis based on estimation of van der Waals strain energies of alkanes, Application In Synthesis of 5340-78-3, the publication is Journal of the American Chemical Society (1976), 98(15), 4567-71, database is CAplus.
The Taft Es parameters were calculated from the difference, ΔΔH,. In the ΔHf° of the neoalkane and the isoalkane where RCMe3 (R = alkyl) was the neoalkane. ΔHf°, estimated by mol. mechanics, gave the relation Es = 4.419 + 0.552.DELTA..DELTA.H with a standard deviation of 0.4 for a total range of 4Es units; the correlation coefficient was 0.94 for the hydrolysis of twenty-four RCO2Et(R = alkyl). Empirically estimated ΔHf° gave poor results.
