Tris(dimethylamido)gallium(III) dimer 1 was synthesised using a modified literature procedure (Figure ). A room temperature suspension of lithium dimethylamide (5.2 g, 102 mmol) in nhexanes (150 mL) was slowly added to a -20 °C solution of GaCl3 (6.0 g, 34.1 mmol) in nhexanes (100 mL) via cannula and the mixture was stirred at this temperature for 1 h. The reaction was slowly warmed to room temperature and stirred for a further 16 h. The reaction mixture was filtered through a pad of Celite and concentrated under reduced pressure to give a solid. The solid was purified by recrystallisation from Et2O at -35 °C to give the compound 1 as a solid (4.61 g, 63%).
