Abstract EN
The specific rates of solvolysis of propargyl chloroformate (1) are analyzed in 22 solvents of widely varying nucleophilicity and ionizing power values at 25.0°C using the extended Grunwald-Winstein equation.
Sensitivities to solvent nucleophilicity (l) of 1.37 and to solvent ionizing power (m) of 0.47 suggest a bimolecular process with the formation of a tetrahedral intermediate.
A plot of the rates of solvolysis of 1 against those previously reported for phenyl chloroformate (2) results in a correlation coefficient (R) of 0.996, a slope of 0.86, and an F-test value of 2161.
The unequivocal correlation between these two substrates attests that the stepwise association-dissociation (AN + DN) mechanism previously proposed for 2 is also operative in 1.
