Abstract
- The Taft's substituent constant of the pentafluorophenyl group is reestimated to be 1.50 by correlation between IR spectral data and sigma constants for a series of esters of 3-phenylpropanic acid and butanoic acid. The pentafluorophenyl group is found to possess the moderate electron-withdrawing ability between 3,5-dinitrophenyl and difluoromethyl groups.
