Abstract

No cycle this time: The first trinuclear alumoxanes [{LAlR(μ-O)} ₂AlMe] (L=CH[C(Me)N(Ar)]₂; Ar=2,6-iPr₂C ₆H₃; R=Me, Et, Ph) with an acyclic Al-O-Al-O-Al core were synthesized (see scheme). The ethyl and phenyl derivatives were characterized by X-ray spectroscopy. When treated with AlMe₃, [{LAlR(μ-O)} ₂AlMe] (R=Me, Ph) gave tetranuclear alumoxanes bearing a (Me ₂AlO)₂ four-membered ring.
