A Strontium Alumanyl

Abstract

The strontium alumanyl, [(BDI)SrAl(SiNDipp)], has been prepared from [(BDI)Sr(BPh4)] and [(SiNDipp)AlK]2. Like its previously described calcium analogue, sructural and computational analysis indicates that the Sr-Al interaction is only marginally involved in the engagement of the Sr cation and alumanyl anion. Unlike its ligher equivalent, however, [(BDI)SrAl(SiNDipp)] does not react with THF, the presence of which only appears to enhance its presumed dismutation and reaction with the toluene solvent at 100 °C to provide a strontium bis-hydrido(meta-tolyl)aluminate.
