The reactivity of lithium (triethylgermyl)triphenylborate, prepared from unsolvated triethylgermyllithium and triphenylborane, with organic substrates in methanol was investigated. The germylborates reacted with organic halides and acyl halides to give the corresponding germyl-substituted compounds. From the reaction with carbonyl compounds, esters, carboxylic acid, alkenes, and alkynes, germylborates were completely recovered.
