摘要：

Reaction of the organolilitiun reagent [Li-{C(SiMe2OMe)(SiMe3)(2)}(THF)(2)] (THF = tetrahydrofuran), 1, with LiAlH4 gave the title organotrihydridoaluminate, 2, which is unusual for an alkali metal organotrihydridoaluminate in being monomeric and in having the Al linked to the Li not only through hydride but also through another of its ligands. The corresponding reaction with AlCl3 gave the title organoaluminum dichloride. The Si-O bonds in 1 and 2 are not significantly lengthened by the O-metal coordination. The bond from Li to the OMe in 1 oxygen is not significantly different in length from that to the THF oxygen.
