Reactions of Ga2Br4*2dioxane with (Trimethylsilyl)methyllithium and Neopentyllithium - Synthesis and Molecular Structure of Lithium Tetraalkylgallanates(III) with Li-C-Ga Bridges.

Ga2Br4*2dioxane 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 alkyllithium in the molar ratio 1:4.The crystal structure of 2 shows a dioxane-brideged dimer and Li-C-Ga bridges with lithium probably bound by the C-H ?-bonds of the cental carbon atom.
