Abstract

The mass spectra of D2 to D11-isomers of dodecenyl acetate were studied using electron impact ionization, high-resoln. data and mass-analyzed ion kinetic energy spectrometry. The principal fragmentation processes of the positional isomerism are dominated by the radical-site rearrangement, double-bond migration and charge transfer along the carbon chain with the aid of rearrangements of hydrogen atoms. The ions of dodecenyl acetates isomerize to a mixture of rapidly interconverting structures prior to fragmentation.

Key words: MASS SPECTROGRAPHY, ISOMER, FRACTURE MECHANISM, CHARGE TRANSFER
