摘要：

Ga2Br4 . 2 dioxane reacts with (trimethylsilyl)methyllithium or neopentyllithium to yield in n-pentane/diethyl ether solution besides elemental gallium exclusively the disproportionation product trialkylgallane. In pure n-pentane the dioxane adducts of the corresponding lithium tetraalkylgallanates (R = -CH2SiMe3 2; R = -CH2CMe3 4) are formed. 2 and 4 are also synthesized by the reaction of GaBr3 with alkyl lithium in the molar ratio 1:4. The crystal structure of 2 shows a dioxane-bridged dimer and Li-C-Ga bridges with lithium probably bound by the C-H sigma-bonds of the central carbon atoms.
