The mass spectra of a series of nuclear substituted styryl ketones with the structureand several relaTed compounds have been determined. The major fragmentation pathways include such processes as an aromatic substitution reaction occurring in the molecular ion as well as the McLafferty rearrangement. Only one of the two possible α-cleavages at the carbonyl function was observed. The major decomposition
已经确定了一系列具有该结构的核取代苯乙烯基酮和几种相关化合物的质谱图。主要的碎裂途径包括分子离子中发生的芳香族取代反应以及麦克拉弗蒂重排等过程。仅观察到羰基官能团处两种可能的 α-裂解中的一种。概述了主要的分解过程,并与最近对 α,β-不饱和脂肪族酮的研究结果进行了比较。建议形成主要碎片离子的机制途径。
