摘　　要：自宏观量合成和分离Ｃ６０以来，人们不断地合成各种功能化的Ｃ６０衍生物［１］．在对Ｃ６０化学性质的认识过程中，气相离子化学一直起着十分重要的作用．Ｂｏｈｍｅ等［２］在ＳＩＦＴ质谱仪上，研究了Ｃ６０的单、双、三电荷离子与水、醇、醚、醛、酮、酯和胺等的气相...Gas phase ion molecule reactions of buckminsterfullerene (C 60 ) with the ion systems generated from the self chemical ionization of alkyl methyl ethers(CH 3OC n H 2n+1 , n= 2, 3, 4 ) were studied in the ion source of a mass spectrometer. The adduct cation C 60 C 2H 5O + and protonated molecular ion C 60 H + were observed as the major products. The former was produced by the reactions of C 60 with the methoxymethyl ion CH 3OCH 2 +, the latter corresponded to the proton transfer reactions from the protonated alkyl methyl ethers to C 60 . It is suggested that the 3+2 cycloadduct is the most favorable structure among the probable isomers with special chemical properties. Our investigation provides the guidance for the synthesis of this compound in condensed phase.
