Abstract

The strontium alumanyl, [(BDI)SrAl(SiN ^Dipp)], has been prepared from [(BDI)Sr(BPh ₄)] and [(SiN ^Dipp)AlK] ₂. Like its previously described calcium analogue, structural and computational analyses indicate that the Sr–Al interaction is only marginally involved in the engagement of the Sr cation and alumanyl anion. Unlike its lighter equivalent, however, [(BDI)SrAl(SiN ^Dipp)] 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.
