摘要
对双 (2_羟基_溴、氯代苯基 )甲烷及其环化的衍生物6_取代_12H_溴氯代双苯并[d,g][1 ,3 ,2]二氧磷杂八环_6_硫化合物进行了质谱分析并探讨了其裂解规律。母体化合物主要在苯基及亚甲基处开裂 ,环合后的衍生物主要以硫和氮原子为中心进行反应。溴、氯代双氧环离子 (m/z422)
Bis(2 _ hydroxy _ bromo _ chlorophenyl)methane(Ⅰ)and its cyclized derivatives—6 _ N _ substituted _ 12H _ bromo _ chlorodibenzodioxaphosphocin _ 6 _ sulfides(Ⅱ,Ⅲ) were analyzed by EI-MS, and the mass spectra were discussed. It was shown that the mass spectra of the cyclized derivatives are rather different from that of the parent compound. In bis(2 _ hydroxy _ bromo _ chlorophenyl) methane, the most important fragmentation occurs on the bond linking the methylene group and one of the phenyl rings. N and S atoms play an important role in cyclized derivatives. The dioxygen _ ring ion(m/z 422)is the characteristic ion for the cyclized compounds(Ⅱand Ⅲ).
