Tertiary a-carbomethoxy-a,a-dimethyl-methyl cations a have been generated by electron impact induced fragmentation from the appropriately a-substituted methyl isobutyrates 1-4. The destabilized carbenium ions a can be distinguished from their more stable isomers protonated methyl methacrylate c and

## Abstract A series of α‐chloro‐ and α‐bromoketimines compounds (1‐9) with different substituents at the α‐position and at the imino group has been investigated by electron impact mass spectrometry as possible precursors of the correspondingly substituted α‐imidoyl carbenium ion, an important clas

## l+-Phenylalky1 )-1-tifluoromethylbenzyl cations and the a-CH,-substituted analogues were generated from the corresponding protonated benzyl alcohols by loss of H,O during chemical ionization (CI). The unimolecular reactions of these ions and of their derivatives specifically deuterated at the 1
