| 中文摘要 | the electron impact mass spectrum (eims) of 3-phenyl-1-butyn-3-ol was reported in this paper. collision-induced dissociation (cid) was used to study the gas phase ion structure of [c8h7](+) formed by the fragmentation of ionized 3-phenyl-1-butyn-3-ol, and that it has the same structure as m/z 103 ions generated by cinnamic acid and alpha-methylstyrene. deuterium labelling, metastable ion (mi) and cid experimental results indicate the formation of m/z 103 ion resulting from molecular ion of 3-phenyl-1-butyn-3-ol, which is a stepwise procedure via twice proton transfers, rather than concerted process during the successive elimination of methyl radical and neutral carbon monoxide accompanying hydrogen transfer. moreover, in order to rationalized these fragmentation processes, the bimolecular proton bound complex between benzyne and acetylene intermediate has been proposed. |
