Summary
The basic dissociation constants for a series of 30 4-aminopyrimidine and 2,4-diaminopyrimidine derivatives were determined in 2% v/v aqueous methanol by a spectrophotometric method. The determinedpK a values correlate well withHammet's σ constants.
Zusammenfassung
Die basischen Dissoziationskonstanten einer Reihe von 30 4-Aminopyrimidin-and 2,4-Diaminopyrimidinderivaten wurden in 2% v/v wäßrigem Methanol durch spektroskopische Methoden bestimmt. Die ermitteltenpK a-Werte korrelieren gut mit den entsprechendenHammett-Parametern σ.
