Abstract

Abstract: The present study is concerned with an evaluation of the effect that a nonconjugated double bond can exert on the well-known fragmentation behavior of carbonyl compounds. Through examination of suitable model compounds and labeled analogs it was demonstrated that double bond migration to the 8, e position (with respect to the carbonyl groups) is favored and leads to a McLafferty rearrangement with charge ...
