Notes:
The thermally and electron-impact-induced rearrangements of the dimethylthioncarbamates to the dimethylthiolcarbamates are discussed. Owing to the competition with the ion fragmentation reactions in the mass spectrometric time, 〈 10-6 seconds, the extent of the mass spectrometrically observed ion isomerization cannot be predicted from that of the thermal induced one. In the ion fragmentations of the non-rearranged molecular ions, it was found that the relative abundance of the ion (CH3)2NC≡O⊕ to the total ionization is larger than that of the ion (CH3)2NC≡S⊕. This is believed to be attributable to the differences in the dissociation energies of the C—S bond and the C—O bond and in the stabilities of the two ions.
