摘要
本文报道了七种4.5-二氧代-2-硫代-1,3,2,4-二氮二磷杂环戊烷衍生物的化学电离质谱(CIMS,甲烷为反应气),结果表明:CIMS中准分子离子MH^+为基峰离子;MH^+离子易发生失去H_2S,CO,C_3H_6等小分子的裂解,(M+C_2H_5)^+离子存在再断裂。
The chemical ionization mass spectra (CIMS) of seven derivatives of 4,5-dioxo-2-thio-1,3,2, 4-diazadiphospholane are reported. The results show that MH^+ ions which tend to frag-mentation by lossing small neutral molecules such as H_2S, CO, C_3 H_6, are the base peak ionsin the CTMS. (M_+C_2H_5)^+ may be refragmented.
