1,1—二氯—2—乙氧基—2—芳基烯烃质谱开裂机理探讨

A Discussion on the Mass Spectrometric Cleavage of 1,1—Dichloro—2—ethyloxy—2—Arylolefins

摘要: 本文报道通过亚稳离子和精确质量测定,讨论了1,1—二氯—2—乙氧基—2—芳基烯烃的质谱裂解规律。提出了主要是经过McLafferty重排,再经过1,3—氢迁移的机理。

Abstract: A study on the mass spectrometric cleavage of 1, 1—dichloro—2—ethyloxy—2—AryIolefins by metastable ions and precise mass measurement is reported. The mechanism via McLafferty rearrangement and then 1, 3—hydrogen shift is suggested.
