Gallium alkoxides: Synthesis and properties

Suslova, Evgeniya V.; Turova, N. Ya.; Mityaev, A. S.; Kepman, A. V.; Gohil, Suresh


Compounds Ga(OR)(3) (R = Me, Et, Pr-i, Bu-n, C2H4OMe) were synthesized by exchange reactions between gallium chloride and alkali metal alkoxides, the reetherefication of Ga(OPri)(3) and Ga(OC2H4OMe)(3) by other ROH (R = Me, Et), and anodic dissolution of metallic gallium in the presence of a electroconductive additive (LiCl, Bu4NBr). When solid GaCl3 is introduced into an alcoholic solution of NaOEt, stable soluble gallium oxoalkoxyhalides are formed. The same reaction with a GaCl3 solution in toluene or electrochemical synthesis produces nonvolatile Ga(OEt)(3) samples, which have the polymer zigzag configuration [Ga(OR)(4/2)(OR)](infinity). Mass spectrometry shows that only Ga(OPri)(3) and freshly prepared X-ray amorphous Ga(OEt)(3) samples (produced by reetherefication) are transferred to the gas phase. The spectra of the latter contain ions generated by penta-and hexanuclear oxoalkoxide molecules, along with fragments of orthospecies [Ga(OEt)(3)](2-4). IR spectra are described for all compounds synthesized.
