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.
三乙基锗和炔烃在钌催化剂的存在下以反式方式发生反应。二氢化锗与 1,3-二炔的钌催化反式氢锗化通过两步加成过程以良好的收率得到 2,5-二取代的锗烯。氢锗化反应成功地应用于 2,2'-双锗烯的合成。
