A simple synthesis of non-solvated trimethylgallium and triethylgallium is proposed based on the reaction of alkyl iodides with a mixture or an alloy of magnesium and gallium in the absence of a solvent or in aliphatic hydrocarbons as solvent.

The reaction of the tetrylenes Ge(ArMe6)2, Sn(ArMe6)2, and Pb(ArMe6)2 [ArMe6 = C6H3-2,6-(C6H2-2,4,6-(CH3)3)2] with the group 13 metal alkyls trimethylaluminum and trimethylgallium afforded (ArMe6)2Ge(Me)AlMe2 (1), (ArMe6)2Ge(Me)GaMe2 (2), and (ArMe6)2Sn(Me)GaMe2 (3) in good yields via insertion reaction routes. In contrast, the reaction of AlMe3 with Sn(ArMe6)2 afforded the [1.1.1]propellane analogue Sn2{Sn(Me)ArMe6}3 (5) in low yield, and the reaction of AlMe3 or GaMe3 with Pb(ArMe6)2 resulted in the formation of the diplumbene {Pb(Me)ArMe6}2 (6) and AlArMe6Me2 (7) or GaArMe6Me2 (8) via metathesis. The reaction of Sn(ArMe6)2 with gallium trialkyls was found to be reversible under ambient conditions and analyzed through the reaction of Sn(ArMe6)2 with GaEt3 to form (ArMe6)2Sn(Et)GaEt2 (4), which displayed a dissociation constant Kdiss and ΔGdiss of 8.09(6) × 10-3 and 11.8(9) kJ mol-1 at 296 °C. The new compounds were characterized by X-ray crystallography, NMR (1H, 13C, 119Sn, and 207Pb), IR, and UV-vis spectroscopies.

The reactions of dialkylgallium hydrides with tert-butylethynylbenzenes - A systematic investigation into the course of hydrogallation reactions

The reactions of bis- and tris(tert-butylethynyl)benzenes with dialkylgallium hydrides afforded two different types of products. 1,4-Di(tert-butylethynyl)benzene and dialkylgallium hydrides R2GaH bearing relatively small substituents (R = Et, nPr) gave the expected addition products with each CC triple bond inserted into a Ga-H bond. The intact GaR 2 groups are attached to those carbon atoms which are in α-position to the benzene rings, and intermolecular Ga-C interactions led to the formation of one-dimensional coordination polymers. In contrast secondary reactions with the release of the corresponding trialkylgallium derivatives GaR3 (R = Et, nPr, iPr, CH2tBu, tBu) were observed for all hydrogallation reactions involving the trisalkyne 1,3,5-tris(tert-butylethynyl) benzene. A similar reaction was observed upon treatment of the 1,4-bisalkyne with a dialkylgallium hydride bearing a relatively bulky substituent (R = neopentyl). Cyclophane type molecules are formed in all these cases with two or three gallium atoms in the bridging positions between both benzene rings. The Royal Society of Chemistry.
Preparation of organogallium compounds from organolithium reagents and gallium chloride. Infrared, magnetic resonance, and mass spectral studies of alkylgallium compounds

, p. 2809 - 2814 (1975)
Conditions for the preparation of a series of base-free trialkylgallium compounds in benzene solvent by the exchange reaction of alkyllithium compounds and gallium chloride are described. Optimum conditions which favor formation of the trialkyl involve mixing a benzene solution of an appropriate alkyllithium compound and a benzene solution of gallium chloride in exactly a 3:1 molar ratio, heating of the reaction mixture for 12 hr at 70°, filtration to remove by-product lithium chloride, removal of solvent under vacuum, and vacuum distillation of the product: 3RLi + GaCl3 = 3LiCl + R3Ga, where R = C2H5, n-C3H7, n-C4H9, i-C4H9, s-C4H9, and t-C4H9. Alkylgallium dichlorides and dialkylgallium chlorides are produced when lithium alkyls and gallium chloride are allowed to react in a 1:1 and 2:1 molar ratio, respectively: nRLi + GaCl3 = nLiCl + RnGaCl3-n, where n = 1 and 2. Reaction of an alkyllithium compound and gallium chloride in a molar ratio in excess of 3:1 results in formation of the corresponding lithium tetraalkylgallate: 4n-C3H7Li + GaCl3 = 3LiCl + LiGa(n-C3H7)4. Trivinylgallium tetrahydrofuranate is produced by the reaction of vinyllithium and gallium chloride in 3:1 molar ratio in tetrahydrofuran solvent. Infrared, proton magnetic resonance, and mass spectra of RnGaCl3-n compounds where R = C2H5 to C4H9 isomers and n = 1-3 are reported and discussed. Proton magnetic resonance spectra reveal that the chemical shifts for protons on α-carbon atoms are sensitive to substitution on the gallium. An explanation for these chemical shift data along with molecular association data for RnGaCl3-n. compounds is given. Mass spectroscopy can be used as a convenient, diagnostic tool for the identification of organogallium compounds of this type. Ion abundance data for all compounds are presented and the fragmentation processes believed to give these ions are discussed.

Paragraph 0032, (2018/02/04)
The invention relates to an efficient purifying method of triethyl gallium, belonging to the technical field of compound purification. The purifying method comprises the following steps of firstly, filtering a crude product of triethyl gallium by using a first chromatographic column with a stationary phase as filler; and then, purifying the filtered crude product of triethyl gallium in a second chromatographic column with a stationary phase as surface grafted filler, wherein the surface grafted filler is filler of which the surface is grafted with tri-n-octylamine. The purifying method disclosed by the invention is combined with a solid-liquid separation means, and a specific coordination agent is loaded on the filler, so that not only is the method simple, but also the purifying effect is further improved.
