Metallation of 2,2,6,6-tetramethylpiperidine, HN[CMe2CH 2]2CH2 (=HL), by H3AlNMe3 in diethyl ether affords a monomeric, Lewis base-stabilised amidoalane Me 3NAlH2L, 1 [Al-Namido, Namine 1.838(2), 2.058(2) Å], whereas treating AlH3 generated in situ with the same amine in diethyl ether yields a remarkably stable secondary amine adduct of alane H3Al(HL), 2 (decomp. > 115°C), also as a monomer in the solid [Al-NHL 2.04(1) Å].
