The Synthesis of Tris(Pentamethylcyclopenta-dienyl)Gallium(III).
Abstract
The previously unknown and elusive compound, Ga(C5Me5)3, has been prepared by several synthetic routes and has been characterized by elemental analyses, IR and 1H NMR data. The compound has been prepared from GaCl3 and excess Na(C5Me5) in THF solution. A second general route to Ga(C5Me5)3, the reaction of Ga(C5Me5)nCl3-n (n=1,2) with sodium naphthalenide in THF solution, has also been realized. Heating of the product mixture at 50-60 C under vacuum leads to the complete removal of the reaction solvent, THF, an observation which suggests that Ga(C5Me5)3 is a very weak Lewis acid. The title compound exists as a pentane and ether soluble colorless crystalline solid with a melting point of 168-170 C.
