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.

Reaction of N(CH2CHRO)3GeBr (2a, b) with LiCCPh affords N(CH2CHRO)3GeCCPh (1a, b) (a, R=H; b, R=Me). Compound (1b) was also obtained by treatment of Cl3GeCCPh (3) with N(CH2CHMeOSnEt3)3 (4). (1a) reacts with N-bromosuccinimide to yield N(CH2CH2O)3GeC(Br)2C(O)Ph (5). Cis-N(CH2CH2O)3GeC(Br)=C(Br)Ph (6) is formed by the reaction of 1a with Br2 in equivalent amounts. All compounds were characterized by 1H- and 13C-NMR spectroscopy and mass spectrometry. Single crystal structures of 1a and 6 were determined by X-ray diffraction studies.
