Fujita, Toshio published the artcileA new substituent constant, ¦Ð, derived from partition coefficients, HPLC of Formula: 1798-04-5, the publication is Journal of the American Chemical Society (1964), 86(23), 5175-80, database is CAplus.
The partition coefficients between 1-octanol and water were determined for 203 mono- and disubstituted benzenes. From these values a substituent constant, ¦Ð, was calculated for 67 functional groups. The constant ¦Ð is defined as: ¦Ð = log Px – log PH, where Px is the partition coefficient of a derivative and PH is that of the parent compound ¦Ð was derived for many of the functions from 8 different systems: benzene, PhNO2, PhNH2, PhOH, benzyl alc., BzOH, phenylacetic acid, and phenoxyacetic acid. Although ¦Ð varies continuously for a given function depending on its electronic environment, the range over which it varies is not great. In certain of the systems, ¦Ð values are related by a simple linear expression.
