Organic Phosphorus Compounds. XI. Quantification of the Alkylation Capacity of Methyl Esters of Diverse Acids of the Tetracoordinated Phosphorus by Means of σP-ConstantsUsing the specific organophosphorus substituent constants σP the alkylation capacity of phosphinic, phosphonic and phosphoric acid esters of the type ABP(O)OCH3 towards trimethyl amine can be described by a common linear relationship \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c}{{\rm lg\, k}_{\rm 2} {\rm = - 2,391 + 1,228} \cdot {\rm \sigma }^{\rm P} } & {{\rm (r = 0,969)}} \\ \end{array}{\rm } $$\end{document} the precision of which is sufficient for practical purposes.
Notes:
Bei Verwendung der phosphorspezifischen Substituentenkonstanten σP gelingt die Beschreibung des Alkylierungsvermögens von Phosphin-, Phosphon- und Phosphorsäureestern des Typs ABP(O)OCH3 gegenüber Trimethylamin durch eine gemeinsame lineare Beziehung \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c}{{\rm lg\, k}_{\rm 2} {\rm = - 2,391 + 1,228} \cdot {\rm \sigma }^{\rm P} } & {{\rm (r = 0,969)}} \\ \end{array}{\rm } $$\end{document} mit einer für praktische Belange ausreichenden Genauigkeit.
