Heterodiatomic multiple bonds have never been observed within Group 13. Herein, we disclose am ethod that generates [(CAAC)PhB=AlCp 3t ]( 1), ac omplex featuring p bonding between boron and aluminum through the association of singlet fragments.W epresent the properties of this multiple bond as well as the reactivity of the complex with carbon dioxide,w hichy ields ab oron CO complex via an unusual metathesis reaction.

Dibenzobismepines may be described as bismuth heterocycles containing two arene functional groups (see the graphic). The coordination chemistry of mono- and dinuclear bismepines has been investigated in solution and in the solid state, demonstrating that they can act as a new class of rigid, ditopic arene ligands. In contrast to the lighter N, P, and As homologues, the bismuth atom does not directly interact with the metal atom but influences the ligand properties through its energetically low lying 6s orbital, its low electronegativity, and its unusual bond lengths and angles. Analytical techniques applied in this work include (DOSY) NMR spectroscopy, single-crystal X-ray analysis, mass spectrometry, and DFT calculations.

9-Aluminafluorenes have only been sparingly investigated and their properties still remain largely unexplored. Herein, we report the synthesis of five aluminafluorene derivatives with a diverse array of aluminium substituents and...

Verbindungen mit heterodiatomarer Mehrfachbindung zwischen Gruppe-13-Elementen sind bislang unbekannt. In dieser Zuschrift berichten wir über eine Darstellungsmethode von [(CAAC)PhB = AlCp 3t ]( 1), einem Komplex, bei dem zwei Singulettfragmente nachAssoziation eine p-Bindung zwischen Bor und Aluminium bilden. Neben den Eigenschaften dieser Mehrfachbindung wird die Reaktivitätv on 1 gegenüber CO 2 präsentiert. Diese führt über eine ungewçhnliche Metathesereaktion zu einer B-CO-Verbindung.
