Abstract

It has been reported2 that in the solvolysis of brosylates 1P and 1s participation by the methoxy group competes with direct displacement by the solvent. Even in the very nucleophilic 100% ethanol, the reaction is essentially com- pletely controlled by kA. Secondary deuterium isotope effects indicate that the solvolysis mechanism of these compounds is best described as an internal displacement reaction, the transition states resembling closely the in- termediate 2.3 In ...
