Sažetak
Rate constants and product selectivities (S) are reported for solvolyses of pentamethylchroman and tri-isopropylbenzene sulphonyl chlorides in acetone/, ethanol/, and methanol/water mixtures, and rate constants for solvolyses of 1-adamantyl methanesulphonate are reported for aqueous binary mixtures with acetonitrile and dioxane. S values show maxima in plots versus % water in alcohol, consistent with the competing reaction channels discussed previously. YQMS derived from rate constants for solvolyses of 1-adam- antyl mesylate correlate with Grunwald-Winstein Y values; there is a small dispersion into separate correlation lines for the various binary mixtures, so the solvation requirements of the sulphonate group in these aqueous mixtures are similar to those for chloride.
