Eine neue Aluminium‐Stickstoff‐Verbindung mit Käfigstruktur

Abstract

Erhit~en von Bis(dimethy1amino)-aluminiumchlorid (1) fuhrt unter partieller Entmethylierung und Entaminierung zu einer snblimierbaren Verbindung A14C14[N(CH3)2]4(NCH3)2 (2). Bessere Ausbeuten an dieser neuen Verbindung, dcr eine Kafigstruktur zugrunde liegt, werden auS 1 in Gegenwart yon B[N(CH&]? oder B2[N(CH3)2]4 erhalten.

Adamantane-Type Clusters: Compounds with a Ubiquitous Architecture but a Wide Variety of Compositions and Unexpected Materials Properties

“…[(NMe2)2AlCl]2 can dimerize under elimination of NMe3 to form [(AlCl)4(NMe2)4(NMe)2] (123), with higher yields achieved in the presence of B2(NMe2)4. [70,71] An anionic derivative [(HAl)4(NPh)6{Li(OEt2)}3] − (in 124, Figure 6) featuring a Li capped adamantane is prepared by the combination of PhN(H)Li and AlH3. [72] The only known Al/P adamantane compound, [(Ar Me6 Al)4(PH2)4(PH)2] (125), is isolated after the reaction of PH3 with [Ar Me6 AlH2]2.…”
