The formation of [CH3CH2C(OH)CH2] from 1‐hepten‐3‐ol

Abstract
The [C4H8O] ion in the mass spectrum of 1‐hepten‐3‐ol is shown to be \documentclass{article}\pagestyle{empty}$ {\rm{CH}}_{\rm{3}} {\rm{CH}}_{\rm{2}} {\rm{C(= }}\mathop {\rm{O}}\limits^{\rm{ + }} {\rm{H}})\mathop {\rm{C}}\limits^{\rm{.}} {\rm{H}}_{\rm{2}} $ by collisional activation spectra, appearance energies and comparison of the ratios of the intensities of metastable decompositions. [C4H8O] appears to be formed by rearrangement of ionized 1‐hepten‐3‐ol to \documentclass{article}\pagestyle{empty}$ {\rm{CH}}_{\rm{3}} \mathop {\rm{C}}\limits^{\rm{.}} {\rm{HC(= }}\mathop {\rm{O}}\limits^{\rm{ + }} {\rm{H)CH}}_{\rm{2}} {\rm{CH}}_{\rm{2}} {\rm{CH}}_{\rm{2}} {\rm{CH}}_{\rm{3}} $ followed by γ‐hydrogen rearrangement‐β‐cleavage.
