Nuclear magnetic resonance studies of boron compounds

Die chemischen Verschiebungen δ14N von 39 Silylaminen [(CH3)3SiNR2, [(CH3)3Si]2NR, [(CH3)3Si]3N und Si-chlorierte Bis(silyl)amine] werden zusammen mit den δ14N- und δ11B-Daten von 19 Silylaminoboranen mitgeteilt. Sie sind mit dem Modell der SiN-(pd). π-Bindung interpretierbar.



Die Borylierung fuhrt zu einem Abschirmungsverlust am Stickstoff. (pp)-π-Bindung zwischen Bor- und Stickstoff sowie geometrische Effekte werden zur Deutung der δ14N-und δ 11B-Daten herangezogen.

The chemical shift data δ14 N of 39 silylamines [(CH3)3SiNR2, [(CH3)3Si]2NR and [(CH3)3Si]3N as well as of Si-chloro-bis(silyl)amines] are reported together with 14N-and 11B-chemical shifts of 19 silylaminoboranes. These data are discussed in terms of the SiN-(pd)-π-bonding model. Borylation of silylamines leads to a deshielding at the nitrogen. (pp)-π-Bonding between B-and N-atoms as well as geometric effects are used for the interpretation of the δ14N- and δ11 B-data.
