| With potassium chloride; sodium chloride at 120℃; under 225.023 Torr; Inert atmosphere; Experimental Procedure 4 Preparation of triethylgallium (TEG) Example 4 Preparation of triethylgallium (TEG) 68.9 g (0.39 mol) of GaCI3, 32.0 g (0.55 mol, 1 .4 equivalents) of dry NaCI and 17.5 g (0.23 mol, 0.6 equivalent) of dry KCI are placed under argon in a 500 ml four-neck flask provided with stirrer, dropping funnel and a separator maintained at 130°C. While stirring, 120.2 g (0.47 mol, 1 .2 equivalents) of ethylaluminium sesquichloride (Et3AI2Cl3) are added in such a way that the temperature in the reaction mixture does not exceed 120°C. The reaction mixture is subsequently heated while applying a reduced pressure of 300 mbar, and Et3Ga is thus isolated (46.6 g; direct yield 75.9%). | A 75.9% B 19% |
