Abstract
The correlation analysis of alkaline hydrolysis and inhihibition
of BuChE with O-alkyl-S-2-dimethylaminoethyl methyl phosphonothiolates
and their tetraalkylammonio derivatives are described.
The logarithm dependence of the rate constants of tQ.ese reactions
at two different temperatures confirms that reactions of
oH- ion and of BuChE with these esters show isokinetic functions
i. e. these esters form isokinetic series.
The correlation analysis with different Hammets constants
showed that alkoxy groups bonded to phosphours1v have somewhat
greater resonance effect (a. = 1.21) in comparison to the inductive
effect in alkaline h ydrolysis reaction.
