摘要

Abstract: The pKCsCHA values are reported for a number of symmetrically meta-and para- substituted diphenylmethanes. The values for the meta series (Me, 33.8; OMe, 32.7; F, 29.9; CF3, 28.9; Ph, 32.3; H, 33.4) give a normal Hammett plot with p= 9.69. The para series (Me, 35.1; OMe, 37.6; Ph, 30.8; NMe2, 38.6; SPh, 28.8; CN, 23.0; S02Me, 22.4) do not fit attempted correlations with u-, the Yukawa-Tsuno modification, or dual substituent ...
