根据甲烷消除反应，均配四甲基没食子酸酯 Lu(GaMe4)3 选择性地与超大体积 (TptBu,Me)H 反应，定量形成单体无碱低配位 (TptBu,Me)LuMe2。 Lu(GaMe4)3 中的强碱性镧系元素甲基与相对较弱的路易斯酸三甲基镓之间的弱相互作用表明，即使在 -35 °C 下，它们也会分离成 [LuMe3]n 和 GaMe3。
Homoleptic tetramethylgallate Lu(GaMe4)3 reacts selectively with superbulky (TptBu,Me)H according to a methane elimination reaction, affording the quantitative formation of monomeric base-free low-coordinate (TptBu,Me)LuMe2. Weak interaction of the strongly basic lanthanide methyl groups with the comparatively weak Lewis acid trimethylgallium in Lu(GaMe4)3 is indicated by their separation into [LuMe3]n and GaMe3 even at −35 °C.
