Ligandenaustausch im System PCI ‐ PBr ‐ ein Beitrag zu Fragen der 31P‐Kernresonanz im Festkörper

Abstract: In äquilibrierten Mischungen von Verbindungen des Typs PX4JX2 (X  Cl; Br) werden die Tetrahalogenophosphonium‐Kationen der allgemeinen Formel [PClnBr4‐n]+ (0 ≤ n ≤ 4) durch die Messung der chemischen 31P‐Verschiebung in Festkörpern nachgewiesen. Die Einsatzmöglichkeiten von konventionellen Hochauflösungs‐ und Breitlinienspektrometern zur Bestimmung der Chemischen Verschiebung in festen Phosphorverbindungen werden diskutiert.

“…Such linear additivity fails down when the substitutions occur from H to Br or from H to I. The deviation from the linearity is observed as U‐shaped or sagging curves of the chemical shifts vs. the number of substituents, which are commonly observed for 27 Al, 29 Si, 119 Sn, and 31 P chemical shifts of tetrahedral and/or pyramidal molecules 4–7…”
