The reaction of [Li(thf)2AlH3{C(SiMe3)3}] 2 with four equivalents of ArOH (Ar = C6H3Pri2-2,6) yielded [Li(thf)-(μ-OAr)22AlH{C(SiMe3)3}] (2) (thf = tetrahydrofuran), which has a structure containing a four-membered LiO2Al ring both in the crystal and in toluene solution. The corresponding reaction with ArOH (Ar = C6H3But 2-2,6) gave a mixture that could not be separated by fractional crystallisation. The reaction of 1 with Ph3SiOH gave [Al(OSiPh3)2-{C(SiMe3)3}(thf)] (3), which was shown by an X-ray structure determination to be monomeric.
