Abstract
The mass spectrum of 1,4-dioxa-8-azaspiro[4.5]decane (4-ethylenedioxypiperidine) showed a prominent peak at m/e 87. Ethylenedioxy ketals commonly give a fragment of m/e 86 and other fragments of higher mass than 87. A mechanism for formation of a m/e 87 fragment was formulated and evidence for this mechanism and the structure of the fragment was obtained by deuterium labelling. Structures and mechanisms of formation of other major fragments were also studied.
