摘要：

Reaction of the anionic tacn ligand (( tacn) H = 1,4-diisopropyl-1,4,7-triazacyclononane) with LiAlH4 in THF afforded a dimeric, unsolvated lithium trihydroaluminate, which upon treatment with terminal acetylenes HCCR (R = Ph, SiMe3) yielded the corresponding monomeric trialkynylaluminates in which one acetylide ligand bridges the Li and Al atom at the C-alpha atom while the two terminal acetylide ligands are coordinated to the Al atom.
