The previously proposed mechanism of the double hydrogen transfer in the molecular ion of 1-methoxy-2-propanol, which yields protonated dimethyl ether and a C 2 H 3 O radical [1], has been re-examined. To obtain a more refined picture of the structur

Negative ion/molecule cycloaddition reactions of 2-methylpropenal in the gas phase

Autor: J. C. Kleingeld, Nico M. M. Nibbering

The gas-phase negative-ion chemistry of 2-methylpropenal has been studied by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR). Deuterium labelling has shown that the gas-phase acidities of the methyl protons and the formyl proton

It is shown on the basis of deuterium labeling that in the metastable molecular ions of N -(5-phenylvaleryl)-1-azacyclopentane-2-thione, decomposing by unimolecular fragmentation, both benzylic hydrogens migrate to the thiolactam ring to generate the
