摘要
在研究二乙胺合三(2-苯骈噻唑基)硼烷的EI质谱时,发现了在EI条件下三(2-苯骈噻唑基)硼烷的二聚作用,并用高分辨质谱、FAB质谱证实了二聚体的存在。用MIKE谱阐明了二聚体离子主要的裂解途径。提出了二聚体形成的一种机理及其可能的结构。
The dimerisation of tri(2-benzothiazolyl)bonrane was discovered in its EI spectrum. The di-mer ions were further confirmed by high resolution mass spectrometry. The main fragmentationroutes of the ions were explained by MIKE spectra; A mechanism for the formation of the di-mer ions and its possible structure of six member ring have also been proposed.
