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

  摘要：

  AbstractA 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 \documentclass{article}\pagestyle{empty}\begin{document}$ {\rm R}_2 \mathop {\rm N}\limits^{\rm + } {\rm = CH}_{\rm 2} $\end{document} ion is suppressed by elimination of a neutral HX particle and [M ‐ HX]+ ion formation, or M‐HX neutral particle ejection and generation of an [HX]+ ion from [M]+˙. Such fragmentation is ensured by the presence of an α‐heteroatom (N, O, P, S) in one substituent (X) and a CO2R type delocalizing group in the α‐position of the other substituent (R2N).

  Provided is a homogeneous catalytic system for use in preparing an ethylene homopolymer or a copolymer of ethylene and α-olefin, and more particularly a Group 4 transition metal compound in which a cyclopentadienyl derivative 3,4-positions of which are substituted with alkyls and an electron-donating substituent are crosslinked around a Group 4 transition metal. Also provided is a method of preparing an ethylene homopolymer or a copolymer of ethylene and α-olefin, having high molecular weight, under high-temperature solution polymerization conditions using the catalytic system including such a transition metal compound and a co-catalyst composed of an aluminum compound, a boron compound or a mixture thereof. The catalyst according to present invention has high thermal stability and enables the incorporation of α-olefin, and is thus effective in preparing an ethylene homopolymer or a copolymer of ethylene and α-olefin, having various properties, in industrial polymerization processes.
