  Unexpected structural integrity of gas phase isoquinoline cations that eliminate HCN

  摘要：

  Abstract13C labelling has been used to study isoquinoline molecular ions undergoing breakdown by HCN elimination in a mass spectrometer. For otherwise stable ions caused to fragment by collisional activation, there is no skeletal rearrangement prior to HCN loss. Of the ions formed by 70 eV electron impact, 69% of those which fragment in the ion source by HCN loss retain their structural integrity, as do 44% of the metastable ions. Of the ions that eliminate HCN without prior arrangement, approximately two‐thirds eliminate C‐1 and one‐third eliminate C‐3. Critical energies are reported for the elimination of HCN from pyridine and isoquinoline molecular ions.

  2-Acyl-3-arylisoxazol-5(2H)-ones give 2-alkyl(aryl)-4-aryloxazoles in good yields at 540°C under flash vacuum pyrolysis conditions, but at higher temperatures the expected oxazoles are accompanied by increasing amounts of isomeric 2,5-disubstituted oxazoles, as well as anilides and decomposition products of the 2,4-disubstituted oxazole. The rearrangement mechanisms have been studied by the use of 13C labelled substrates and p-substituted 3-arylisoxazolones. The 2,5-disubstituted oxazoles are considered to arise from 1H-azirines, and the anilides from the nitrone ketene isomer of the acylisoxazolone.

  2-酰基-3-芳基异噁唑-5(2H)-酮在 540°C 的闪速真空条件下产生 在 540°C 的闪蒸真空热解条件下，可以得到产率很高的 2-烷基（芳基）-4-芳基噁唑。 但在更高温度下，预期的噁唑会伴随着越来越多的异构体出现。 但在更高温度下，预期的噁唑会伴随着越来越多的异构 2,5-二取代噁唑，以及苯胺和分解物。 以及苯胺和 2,4-二取代噁唑的分解产物。 对重排机理的研究采用了 13C 标记的底物和 对取代的 3-芳基异噁唑酮。2,5-二取代的 噁唑被认为来自 1H-吖嗪，而苯胺则来自腈。 苯胺类则来自酰基异噁唑酮的腈酮烯异构体。
