Quasi-thermoneutral P -> B interactions within Di- and tri-phosphine boranes
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(2)P)C6H4](2)BPh (2) and [o-(iPr(2)P)C6H4](3)B (3).
