摘要 报道了3种含双官能团苯基醚化合物2-(2,6-二氯苯氧基)丙睛、N-羟基-4-丁氧基苯乙酰胺、2-(1-甲基乙氧基)苯酚甲氨基甲酸酯的电子轰击质谱碎裂.用亚稳分析和低能碰撞诱导解离研究了3种化合物的分子离子碎裂规律,除简单的直接键断裂外,还证实经历了离子/中性(碎片)复合物中间体的单分子解离反应同时存在的竞争机理,解释了观察到的分子内单氢迁移、双氢迁移现象. The fragmentations of three bifunctional phenylether compounds including 2-(2,6-dichlolo )phenoxyl propionitrile, N-hydroxyl-4-butoxyl phenylacetyl amine (bufexamc) and 2- (1-methylethoxyl ) phenol methylcarbamate (Propoxur) under electron impact ionization were reported. Metastable ion(MI) and collision-induced dissociation(CID) at a low energyhave been used to study the fragmentation pathways from molecular ions. Apart from the simple bond cleavages, and the unimolecular dissociations via ion/neutral complex intermediate as a competitive mechanism were demonstrated- Moreover, the intramolecular hydrogen transfer and double hydrogen transfers in the fragmentations of these compounds were discussed in detail.
