Abstract

Abstract: The kinetics of closure of 1, I-bis (ethoxycarbony1) cycloalkanes from the anions derived from diethyl (w-bromoalky1) malonates have been investigated in Me2S0 at 25'C. Rate constants and effective molarities (EM) have been obtained for the ring sizes 4-13, 17, and 21. This is the first quantitative study on the kinetics of SN2 closure of all-carbon rings, which includes small, common, medium, and large rings. The reactivity data span over ...
