AbstractThe influence of n‐butyl group position upon the fragmentation behavior of the three isomeric n‐butylcyclohexanones was studied. The different fragmentation processes are described and have been applied to the differentiation of the positional isomers of long‐chain n‐alkylcyclohexanones. In the case of the 4‐n‐alkyl isomers, an interesting mechanism involving a recyclization is proposed and substantiated by deuterium labelling.
