Gaseous 1-methyl-1-oxoniacycloalkanes as stable intermediates on the C3H7O+ and C4H9O+ potential energy surfaces
Abstract
The nature and the isomeric distribution of the neutral products obtained from the gas-phase attack of CH5+, C2H5+, and CH3FCH3+ ions on cyclic CnH2nO(n= 2,3, and 4) ethers provide the first experimental evidence in favour of 1-methyl-1-oxoniacyclopropane and 1-methyl-1-oxoniacyclobutane as stable intermediates on the corresponding potential energy surface.
