Yamagami, Chisako published the artcileHydrophobicity parameter of diazines. 1. Analysis and prediction of partition coefficients of monosubstituted diazines, HPLC of Formula: 31401-45-3, the publication is Quantitative Structure-Activity Relationships (1990), 9(4), 313-20, database is CAplus.
The octanol/water partition coefficient (P) of a number of monosubstituted diazines was measured. The composition of the π value of substituents, the increment in the log P value accompanying the introduction of substituents, was examined in terms of physicochem. substituent parameters and correlation anal. The diazine-π value of substituents was generally higher than the pyridine-π value of corresponding substituents, indicating that the intramol. electronic interactions between the ring-N atoms and substituent are more pronounced than those in substituted pyridines in governing the log P value of the mol. Except for 2-substituted pyrimidines, the π value of substituents in each series of monosubstituted diazines was in general nicely correlated with the π value of the corresponding substituents in substituted pyridines along with electronic parameter terms representing bidirectional electronic effects on the relative solvation of the ring-N atom(s) and the hydrogen-bondable substituents with partitioning solvents according to the procedure proposed previously for the anal. of the π value in disubstituted benzenes and monosubstituted pyridines. Keeping in mind that 2-pyrimidines substituted by hydrogen-bondable groups sometimes behave as outliers, the correlations were believed to be usable for prediction of log P values of monosubstituted diazines.
