Synthesis, Structure, and Reactivity of a Monomeric Iminoalane

Abstract: Monomeric iminoalane: A donor‐stabilized monomeric iminoalane was prepared by the reaction of 1 with an N‐heterocyclic carbene (see scheme). The X‐ray structure exhibits a very short AlN bond of 1.705(4) Å, which suggests multiple‐bond character. Treatment of the iminoalane with phenyl acetylene, aniline, and carbon monoxide resulted in addition reactions to the formal AlN bond, thus indicating that the AlN multiple bond is highly reactive.

“…5). 59,60 This clearly demonstrates the role played by ancillary ligands coordination in destabilizing the Al(I) species and triggering BDI degradation. 55 This phenomenon appears to be promoted by the coordination of sigma donors, which destabilize the low-valent metal species.…”

“…Dies erinnert an die Al = N-Doppelbindung eines kürzlich verçffentlichten Iminoalankomplexes. [53] Tatsächlich Die ungewçhnliche Bindungssituation der Verbindung 1 soll weiterhin in Bezug auf die einzigartige Darstellungsmethode diskutiert werden. Diese wird aufgrund der vor-ausgegangenen Arbeiten in der Borylenchemie postuliert, [57][58][59] und geht von einer Assoziation eines kurzlebigen Borylens mit dem Al I -Komplex aus.B eide Edukte liegen in einem Singulettgrundzustandv or.…”

“…[9] Innerhalb der Gruppe 13 ist ein solches Bindungsmotiv bislang unbekannt. Tatsächlich geht Aluminium nur eine Mehrfachbindung [49] mit sich selbst, [28] den Chalkogenen, [50,51] Stickstoff [52,53] und den Übergangsmetallen ein. [54] In den meisten Beispielen enthalten heterodiatomare Aluminiumkomplexe stark polarisierte Bindungen und einen partiellen Anteil einer Doppelbindung.…”
