The unusual gas-phase rearrangements of deprotonated alkyl N-allyloxycarbamates and related species

Abstract

The negative ion spectrum of MeOCO N OCH 2CHCH 2 shows a major peak corresponding to the methylcarbonate anion MeOCO − 2. Evidence is presented which suggests that this is formed by the successive rearrangement pathway ▪ The first step could involve either a 1,2 or 1,4 anionic rearrangement; the second step is a 1,2 anionic rearrangement.
