摘要：

The dihydronaphthalene elimination reaction between Na-2[C10H8(GaR2Cl)(2)}] (R = CH2CMe3, CH2CMe2Ph) and t-BuNH2 provided a room-temperature route to [R2GaNH(t-Bu)](2). However, when Ga(CH2CMe2Ph)(3) and t-BuNH2 were reacted at 140-150 degrees C, C6H5CMe3 was eliminated and the product was [(H4C6)Me2CCH2]Ga[NH(t-Bu)](2)Ga(CH2CMe2Ph)(2), a gallium-(III) amide with one GaC4 metallocyclic ring, rather than [(PhMe2CCH2)(2)GaNH(t-Bu)](2). X-ray structural studies confirmed the identity of this novel compound as well as that of the typical dimer. When the reaction temperature was increased to 210-230 degrees C, the product was [(H4C6)Me2CCH2]Ga[NH(t-Bu)](2)Ga[CH2CMe2(C6H4)] a species with two GaC4 metallocyclic rings.
