Low Oxidation State Gallium Compounds. Synthesis and Characterization of Ga(CH2CMe3)n
Abstract
The new organogallium(I) compound (Ga(CH2CMe3))n has been prepared by the reduction of Ga(CH2CMe3)2Cl by using either sodium or lithium with naphthalene in THF. When the reagents were combined at -78 deg C, a yellow intermediate, a neopentylgallium(III) derivative of dihydronaphthalene C10H8(Ga(CH2CMe3)2)2 (dot) 2 MCl (M = Li, Na) was formed. Warming of the solution to 0-25 deg C resulted in decomposition of the yellow intermediate and formation of a reddish brown solution of Ga(CH2CMe3))n, Ga(CH2CMe3)3, C10H8, and either NaCl or LiCl. The gallium(I) product was a vitreous solid and was characterized by complete elemental analyses, hydrolyses with HC1/H20 and with DCl/D20, oxidation with HgCl2 and with I2, cryoscopic molecular weight studies in benzene solution and IR and NMR spectroscopic studies. All data support the conclusion that (Ga(CH2CMe3))n exists as a mixture of species which are gallium cages. The numbers of gallium atoms in these cages might range from 6 to 12 atoms.
