| Abstract |
The extended Grunwald-Winstein equation can be expressed as in equation (1) ; k and ko represent the specific rates of solvolysis of a substrate RX in a given solvent and in the standard solvent (80% ethanol), respectively; l is the sensitivity of the solvolysis towards changes in solvent nucleophilicity (NT); m is the sensitivity of the solvolysis towards changes in solvent ionizing power (YX, for a leaving group X); and c is a constant (residual) term. In this work, we investigated the solvolyses of phenyl 4-methylphenoxy thiophosphinyl chloride in pure solvents and mixed binary solvents to obtain an exact kinetic information in various solvents .
log (k/ko) = l NT ＋ m YX ＋ c ( 1 )
