Abstract

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-N_amido, N_amine 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-N_HL 2.04(1) Å].
