Abstract
The kinetics of solvolysis of 2-cyclopentylethyl, 2-(Δ2-cyclopentenyl) ethyl and 2-(Δ3- cyclopentenyl) ethyl p-nitrobenzenesulphonates (I, II and III, respectively) and the corresponding 1, 1-di-deuterated analogs, I-d2, II-d2 and III-d2, were studied in 25% water- 75% dioxane and in glacial acetic acid at a number of temperatures. The very small k/kD values observed for I and I-d2 suggest considerable SN2 character for the solvolysis of ...
