Vinyl-trisubstituted germanes react selectively with terminal alkynes in the presence of compounds containing Ru−H and Ru−Ge bonds with formation of functionalized alkynylgermanes. The reaction opens the first transition metal catalytic route for the preparation of this class of organogermanes, which are useful reagents for organic synthesis. The mechanism elucidated by NMR spectroscopic study of stoichiometric reactions shows that this process is a new ...
