Abstract

Abstract Substituenten in der sterisch unwirksamen p-Stellung zum Mesitylsubstituenten bewirken eine lineare Variation der Aufspaltung zwischen o-und p-Methylgruppensignalen mit der nach einer ab-initio-Methode oder nach der CNDO 2-Methode berechneten π- Elektronenladungsdichte in p-Stellung bei den entsprechenden monosubstituierten Benzolderivaten. Ebenfalls eine gute Korrelation wird mit Hammett-σ p-Konstanten und ...
