Abstract
Evidence is presented which suggests that the anionic isomers MeO–CH2–CC– and CH2 CC––OMe, upon collision activation in the gas phase, fragment through the vinylidene carbene intermediate [(CH2 CC:)MeO–]. In particular, the intermediate eliminates CH2O and MeOH to form C3H3 – and C3H–, respectively. Ab initio calculations indicate that the latter ion has a ground state triplet structure with ‘allenic’ type geometry.Keywords
