Abstract

The first examples of five coordinate aluminum acetylide compounds chelated by a single ligand are reported in this paper. The combination of L(^tBu)AlCl (where L=Salen (1), Salpen (2), Salophen (3), Salomphen (4)) with LiC≡CPh in THF at-78 °C leads to the formation of the four acetylides (5-8), LC≡CPh. These are extremely moisture sensitive and readily hydrolyze to form aluminum hydroxides and with condensation form compounds of formula [L(^tBu)Al]₂O. The hydrosylate [Salophen(^tBu)Al]₂O (9) has been structurally characterized.
