Mass spectrometry of organic compounds of the group V Elements: VI—A new type of amine fragmentation under electron impact

Autor: V. N. Voznesensky, Remir G. Kostyanovsky, Yu. I. El'natanov, G. K. Kadorkina

Publikováno v: Organic Mass Spectrometry. 15:412-418

A new type of amine fragmentation under electron impact is elucidated for proline, sarcosine and aspartic acid derivatives and aminomethylphosphines of the general formula R2NCH2X. Ordinary α-cleavage affording the ion is suppressed by elimination o

Mass spectrometry of organic compounds of the group V elements: V-Cyanamides, cyanphosphines, cyanarsines and vinylogues

Autor: Yu. I. El'natanov, R. G. Kostyanovsky, V. N. Voznesensky, A. P. Pleshkova

Publikováno v: Organic Mass Spectrometry. 15:397-411

New data have been obtained confirming distinct differences in fragmentation of compounds of trivalent nitrogen and other group V elements under electron impact. These data have been obtained for the fragmentation of the cyanamides, cyanphosphines an

Mass spectrometry of organic compounds of group V elements 7—N-alkoxyamines

Autor: V. N. Voznesensky, Remir G. Kostyanovsky, V. F. Rudchenko, A. P. Pleshkova, S. Sh. Trokhova

Publikováno v: Organic Mass Spectrometry. 19:113-127

The suggestion of participation of the participation Ione electron pair of the nitrogen atom in amine-type stabilization has been confirmed by a decrease in amine-type fragmentation and a drastic change in the decomposition routes under electron impa

Mass spectrometry of organic compounds of the group V elements. IV—new data on amines, phosphines, arsines and the corresponding acyl derivatives

Autor: A. P. Pleshkova, V. N. Voznesensky, R. G. Kostyanovsky, Yu. I. El'natanov

Publikováno v: Organic Mass Spectrometry. 11:237-257

Further investigations have given new data confirming differences in fragmentation under electrol impact of compounds of trivalent nitrogen and other group V elements. These data have been obtained by comparision of the fragmentation of the amines, p
