Abstract
The influence of substituents on the half-wave potentials for the polarography of 9-benzylidenefluorenes in 68·1% methanol has been examined. The same linear correlation with Hammett σ-values and ρ=+0·23 volt is found for substituents on both the benzyl group and the fluorene ring. The half-wave potentials for substituted 3-phenylcoumarins in 68·1% methanol show two linear correlations with Hammett σ-values. Substituents on the phenyl group have ρ=+0·11 volt and substituents on the coumarin ring have ρ=+0·33 volt.
