Reactivity of electron impact ionized large-ring cycloalkylamines. Loss ofCnH2n + 1. Alkyl radicals from long-chain aliphatic compounds with a terminal enamine or ester function (lipids)
摘要:
AbstractLarge‐ring Cycloalkylamines rearrange after electron impact ionization into long‐chain enamines. A general mechanism is proposed for their fragmentation, and a parallel is established with the fragmentation of long‐chain esters (lipids). It is shown that the parent ions rearrange into a series of interconverting branched onium ions from which alkyl radicals are lost. The mechanism of the interconversion is discussed.
