The selective introduction of fluoroalkylated vinylmetals in controlled strategies
is a challenging process for many chemists. This study reports the highly regio- and
stereoselective synthesis of functionalized vinylgermanes bearing a perfluoroalkyl
group from perfluoroalkylated acetylenic esters via AlCl3-catalyzed hydrogermylation. Regio- and stereoselectivity are highly dependent on
the nature of the catalyst and the nature of the fluoroalkyl group of alkyne.
