Mass Spectrometric Study of Some Dimethylindium Cyclic Imides

Abstract: The electron ionization mass spectrometric behaviour of a series of dimethylindium derivatives with piperidine, pyrrolidine, azetidine and methylaziridine were investigated. These data have been compared with data from mass-analysed ion kinetic energy spectrometry. Fragmentation patterns of the complexes in question give information relevant to their gas-phase behaviour as precursors for III-V semiconducting materials via metalorganic chemical vapour deposition.Design of new high technologies in semiconductor … Show more

“…It was characterised by mass-spectrometry, 1 H and 13 C NMR spectroscopy and X-ray structure analysis. Assignment for both 1 H and 13 C resonances were made on the basis of the relative chemical shifts in comparison with the NMR spectra of the nearest analogue, adamantan-2-ol, previously studied by us in detail using a suitable combination of 1 H-1 H and 1 H-13 C correlation experiments [25]. The analytical data and interpretation of the NMR spectra are shown in the Table 1.…”

“…the main decomposition product is Et 2 In , then for the piperidine analogue the main part of the ionic current is due to the fragment EtInL , formed as a result of ethyl elimination. Here we have to mention that any decomposition of the heterocyclic ligands was not observed by us for the corresponding compounds of dimethylindium, 3 whilst the remarkable significance was the elimination of both methyl groups.…”

“…The fragmentation patterns of all complexes under investigation show quite low intensities of dimeric molecular ions and their derivatives, when compared to the corresponding dimethylindium analogues. 3 This means that either dimers of diethylindium amides are not stable thermodynamically and monomerize upon evaporation, or these complexes are present as a mixture of mono-and dimer forms. For the coordination compounds under discussion, except the deriva- tives containing thee-membered rings, the fragmentation occurs according to quite similar schemes where Et 2 In is the main product.…”
