Quasi-thermoneutral P → B interactions within di- and tri-phosphine boranes
Résumé
Spectroscopic, structural, and theoretical evidence is provided for both open (no intramolecular P → B interaction) and closed (with intramolecular P → B interaction) forms of the di- and tri-phosphine boranes [o-(iPr 2P)C6H4]2BPh (2) and [o-(iPr 2P)C6H4]3B (3). © 2007 American Chemical Society.
