摘要
报道并讨论了一系列1,3,5-三烷基硼嗪B3H3N3R3(R = Et, Prn, Pri, Bun, Bu8, Bui, But)的质谱。光谱的主要特征是由分子离子中n取代基的α-碳原子裂解烷基自由基而产生的一群离子。这些片段与烷基苯的质谱中观察到的苯或tropyum离子是等电子的。对1,3,5-三乙基硼嗪的进一步裂解路径进行了描述，并通过对氘化衍生物的研究得到了支持。
Borazines. Part V. The mass spectra of some 1,3,5-trialkylborazines
The mass spectra of a series of 1,3,5-trialkylborazines, B3H3N3R3(R = Et, Prn, Pri, Bun, Bu8, Bui, But) are reported and discussed. The dominant feature of the spectra is a group of ions which arise through cleavage of an alkyl radical from the α-carbon atom of an N-substituent in the molecular ion. These fragment species are isoelectronic with the benzyl or tropylium ions observed in the mass spectra of alkyl benzenes. Further fragmentation paths are described and are supported in the case of 1,3,5-triethylborazine by studies on deuteriated derivatives.
