摘要
介绍十三种新的２－取代亚胺基－３－［Ｎ－（２－氯乙基）］氨甲酰四氢噻唑化合物的电子轰击（ＥＩ）质谱及其分子离子峰。它们的特征峰为ｍ／ｚ［Ｍ—１０５］＋，［Ｍ—４９］＋，［Ｍ—３５］＋，１０５，５６等。其中Ｍ—１０５碎片的强度较大（大多为基峰）。据此，提出了它们经电子轰击断裂的可能途径──麦克拉弗蒂重排（ＭｃＬａｆｆｅｒｔｙＲｅａｒｒａｎｇｅｍｅｎｔ）。
he EI mass Spectra and the molecular ion peak [M]+ and [M+2]+ of 2-Substitutedimno-3-[N-(2-Chloroethyl)] Carbamoylthiazolidines were investigated, the characteristic peaks being m/z:[M-105]+, [m-49]+, [M-35]+,105, 56 etc. , and the relative intensity of M-105 fragment being all higher than the others. Based on these results, a possible pathyway──McLafferty Rearrangement for fragmentation is suggested.
