摘要

Abstract Dissociative ionization of 1, 2-epoxy n-alkanes gives rise to abundant [C 4 H 7 O]+ ions of structure [CH 3 OCHCHCH 2]+. This conclusion is drawn from metastable ion analysis and from collisional activation spectra. This fragmentation involves the C [BOND] C ring opening and a 1, 4-H migration leading to the corresponding enol ether [CH 3 OCHCHCH 2 R]+. precursor of [CH 3 OCHCHCH 2]+ fragment. The same isomerization ...
