Abstract

Abstract The main process of the electron impact induced water elimination of the title compounds takes a reaction course comprising several individual steps. A characteristic neighbouring group participation of the carbonyl function is involved, onto which a hydrogen is transferred in a first rate-determining reaction step. This rearranged hydrogen is finally lost together with the hydroxyl group. The reaction of N-(2′-hydroxyethyl) piperidone follows ...
