The addition of germatrane, HGe(OCH2CH2)3N (1), to terminal acetylenes is catalyzed by [Cp*RhCl2]2 and yields styrylgermatranes. The stereochemistry of the double bond can be controlled by the choice
Palladium-catalyzed cross-coupling reactions of allyl, phenyl, alkenyl, and alkynyl germatranes with aryl iodides

The potential of using organogermatranes in palladium-catalyzed cross-coupling with aryl iodides has been investigated. We have found that organogermatranes are less reactive in this analogue of Stille coupling than trialkylorganostannanes; nevertheless activation by fluoride promotes the reaction. The hypervalent germanium species produced from the germatranes provide a more efficient and more easily handled reagent than trialkoxygermanium analogues.
