Reaction Conditions:

with gallium(III) trichloride at 50 - 100; for 1 - 3 h;Heating / reflux;

Steps:

1; 2; 3 Example 1
[0044] Five grams of gallium trichloride and 2.8 g of triethylboron (1:1 molar ratio) are added to a flask equipped with a condenser under a nitrogen atmosphere. The reaction is performed neat, i.e. no solvent is used. The reaction mixture is heated to 50° C. and maintained at that temperature for one hour. The reaction mixture is analyzed by FT-NMR and shows the presence of triethyl gallium: 1H NMR; δ1.08 (CH3, t) and 0.45 (CH2, q). The chemical shifts for triethylboron are also distinguished at δ=0.91 (CH3, t) and 1.12 (CH2, q). EXAMPLE 2 [0045] Five grams of gallium trichloride and 4.2 g of triethylboron (2:3 molar ratio) are added to a flask equipped with a condenser under a nitrogen atmosphere. The reaction is performed neat. The reaction mixture is heated to 60° C. for one hour. A slight reflux is observed and a partial takeoff distillation head is attached to the flask to collect the refluxing material. The reaction flask is heated to 70° C. and a small amount of the refluxing material is collected. The reaction mixture and the distillate are analyzed by FT-NMR and show the presence of triethyl gallium. EXAMPLE 3 [0046] Fifteen grams of gallium trichloride and 8.4 g of triethylboron is added to a reaction flask equipped with a condenser under nitrogen. The reaction mixture is heated at 100° C. for three hours A partial takeoff distillation head is attached to the reaction flask. The reaction mixture is then heated to 90° C. A small amount of refluxing material is collected. The distillate and the refluxing material are analyzed by FT-NMR and show the presence of trimethyl gallium in the distillate.
