Reactions of Me2Si(OR)(NHR′) (R = 2,6-Me2-Ph; R′ = Cy (2a), Ph (2b)) with AlMe3 in pentane at room temperature afford unusual dinuclear aluminum complexes (Me2Al)2[(μ-OR)(μ-NR′SiMe3)] (R = 2,6-Me2Ph; R′ = Cy (3a), Ph (36)) that contain both nitrogen- and oxygen-bridging groups. Meanwhile, the corresponding reaction of Me2Si(OR)(NHR′) (R, R′ = 2,6-Me2Ph (2c)) yields a monomeric N,O-chelated aluminum species [Me2Si(OR)(NR′)]AlMe2 (3c). It is most likely that two AlMe3 molecules are associated with the facile cleavage of the Si-O bond to form the stable four-membered (μ-N)Al2(μ-O) ring of 3a,b, but the analogous reaction does not occur in 2c, having a bulkier N-substituent. The crystal structure of 3a is reported.
