- Аннотация: Synthesis of acetylacetonate derivatives of a series of ortho-palladated complexes based on secondary and tertiary alpha-arylalkylamines was described. Their structures and stereochemistry were elucidated by IR, UV, IH NMR, and CD spectra. Fragmentation processes of these complexes and some model compounds were studied by mass spectrometry (EI). An unusual rearrangement of a molecular ion involving migration of the hydrogen atom from the alkylaminoalkyl group to the palladium atom to form a hydride intermediate followed by the elimination of PdH was observed. The rearrangement occurs through isomerization of the k2-O,O'-coordinated beta-diketonate ligand to the eta1-C-bonded diketonyl form to give the coordinationally unsaturated metal center.
