Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The molecular ions of phthalimidoalkyl-α-diazoketones that form in the gas phase under electron impact split out a nitrogen molecule and rearrange by a Wolff mechanism to ketenic ions. The alternative intramolecular heterocyclization does not occur. The decomposition mechanism of [M-N2]+ions was studied. The structures of some charged fragments that form when the phthalimide nucleus decomposes were established by high resolution spectrometry,
