Abstract

Abstract: a-Dialkoxyalkyl carbocations R'C (OR)*+ were produced in aqueous solution by H abstraction from acetals by OH and H radicals followed by one-electron oxidation of the so- formed a-dialkoxyalkyl radicals. Rate constants for the reactions of the cations with H 2 0 (and in some cases OH-) have been determined by using time-resolved conductance techniques. For example, MeC (OMe)*+ reacts with water with a rate constant of 1.3 X lo5 ...
