Abstract

Abstract The positive ion mass spectra of several chromium (III) β-diketonates with aliphatic α-substituents have been investigated. Metastable peaks in the spectra confirm that ions containing substituents with γ-H atoms undergo propene loss. This implies a McLafferty rearrangement of an open-chain ligand structure. Ethyl radicals are lost from n-butyl substituents; methyl groups are cleaved from the molecular ions of complexes formed from ...
