Abstract: UV, ionization consts. (pK'), and proton chem. shifts of the hydroxyl group δ(OH) of eight 3'- and 4'-substituted 2-hydroxy-5-methylbenzophenones were measured. A satisfactory σ/ρ correlation for pK' and δ(OH) was found. However, the slope value of these relations indicated that the transfer of electronic effect was ∼5 times smaller than that in the case of substitution on the ring bearing the OH.
