Preparation of Molecular Alumoxane Hydrides, Hydroxides, and Hydrogensulfides

Abstract

Suppressed aggregation: The unprecedented alumoxane hydrogensulfide [{LAl(SH)}2(μ-O)] and the unique sulfide-bridged compound [{LAl(SH)}2(μ-S)] can be prepared from the easily accessible aluminum dihydride [LAlH2] (L=HC[(CMe)N(2,4,6-Me3C6H2)]2−). Owing to the cis conformation of the terminal SH groups, these compounds represent ideal precursors for the synthesis of heterometallic compounds.
