Abstract
Reaction of triethylgermane and alkynes in the presence of a ruthenium catalyst occurred in a trans fashion. The ruthenium-catalyzed trans-hydrogermylation of 1,3-diynes with dihydrogermanes afforded 2,5-disubstituted germoles in good yield through a two fold addition process. The hydrogermylation reaction was successfully applied to synthesis of 2,2'-bigermole.
