chloride compounds [2,6-(4-tBuC 6 H 4 ) 2 C 6 H 3 } 2 GaCl] (1), [2,6-(3,5-Me 2 C 6 H 3 ) 2 C 6 H 3 } 2 GaCl] (2), [2,6-(4-tBuC 6 H 4 ) 2 C 6 H 3 } 3 Ga] (3), [(2,6-Mes 2 C 6 H 3 } 2 AlCl] (5), and [(2,6-Mes 2 C 6 H 3 ) 2 AlH] (7; Mes = 2,4,6-Me 3 C 6 H 2 ). While the gallium compounds can be obtained at room temperature, heating is required for the aluminum derivatives. The dibutyl compounds [(2,6-Mes
两个或三个当量的反应。间三联苯锂与 MCl 3 或 AlH 3 ·NMe 3 (M = Al, Ga) 生成双(三联苯)-铝和氯化镓化合物 [2,6-(4-tBuC 6 H 4 ) 2 C 6 H 3 } 2 GaCl] (1), [2,6-(3,5-Me 2 C 6 H 3 ) 2 C 6 H 3 } 2 GaCl] (2), [2,6-(4- tBuC 6 H 4 ) 2 C 6 H 3 } 3 Ga] (3)、[(2,6-Mes 2 C 6 H 3 } 2 AlCl] (5)和[(2,6-Mes 2 C 6 H) 3 ) 2 AlH] (7; Mes = 2,4,6-Me 3 C 6 H 2 ). 虽然可以在室温下获得镓化合物,但铝衍生物需要加热。二丁基化合物 [(2, 6-Mes 2 C 6 H 3 )GaBu 2 ] (8) 和 [(2,6-Dipp 2 C 6 H 3 )GaBu2]
