【摘要】 本文报道两种单取代苯并氮杂冠醚(1)和四种双取代苯并氮杂冠醚(2)的电子轰击(EI)质谱及其分子离子峰。化合物(1)的特征峰,m/z 372,342,236,192,136,121,109,56;化合物(2)的特征峰:m/z[M-109]~+,[M/2]~+,[M/2±13]~+等。据此提出了单取代和双取代苯并氮杂冠醚经电子轰击断裂的可能途径。更多还原

【Abstract】 The EI mass spectra and the molecular ion peak[M]~+ of two mono-substituted azacrown ethers(1)and four di-substituted azacrown ethers(2)were in-vestigated,the characteristic peaks being m/z 372,342,236,192,136,121,109,56 for compounds 1,and m/z[M-109]~+,[M/2]~+,[(M/2)±13]~+ etc.for compounds-2.Based on these results,a possible pathway for fragmentation was suggested.更多还原
