Reactions of β-diketiminatoaluminum hydrides with tert-butyl hydrogenperoxide - Facile formation of dialuminoxanes containing Al-O-Al groups

Treatment of diphenyl-β-diketiminatoaluminum dihydride, LAlH2 [1, L = {H5C6-N{double bond, long}C(Me)}2CH] with neopentyl- or trimethylsilylmethyllithium afforded the corresponding alkylderivatives LAlH(R) [R = CH2-SiMe3 (2), CH2-CMe3 (3)] by the precipitation of lithium hydride. Deprotonation of a methyl group instead of salt elimination occurred by the similar reaction of the more basic alkyllithium compound LiC(SiMe3)3. The reactions of the hydrides 1-3 with tert-butyl hydrogenperoxide did not yield the expected peroxo derivatives, instead the dialuminoxanes LAl(R)-O-Al(R)L [R = OCMe3 (5), CH2SiMe3 (6), CH2CMe3 (7)] were isolated in high yields. Their Al-O-Al bridges deviated from linearity and had Al-O-Al bond angles of about 155° on average.
