【摘要】 采用相转移催化反应合成了两个不饱和脂环氮杂冠醚。利用红外光谱、核磁共振谱、质谱测定了他们的结构。特别是利用高分辨质谱、碰撞诱导裂解、质量分析离子动能谱对它们的质谱特性进行深入研究 ,提出了可能的碎裂途径。由于两个化合物的结构类似 ,所以它们的质谱有相同之处 ,但环大小和取代基不同 ,也有明显的差别更多还原

【Abstract】 In this paper, two unsaturated alicyclic nitrogen heterocyclic crownethers were synthesized by phase transfer reaction .The structure was identified by means of IR, NMR and MS. Especially, their mass spectra were discussed in detail by using the high resolution mass spectrametry, collision induced dissociation(CID) and Mass Analysed Ion Kinetic Energy Spectroscopy(MIKES). The possible fragmentation pathway was presented. The results revealed that there were some differences between the mass spectrometric behavior of these two compounds because of the effect of the size of ring and different substituted group attached to ring such as toluenesulfonyl, furyl and phenyl.更多还原
