Metal nanoparticles exhibit unusual chemical and physical properties and have potential to serve as hybrid catalysts.&lt;span style="font-size:10.8333px"&gt; &lt;/span&gt;Our laboratory has been exploring the synthesis and utilization of nanocluster catalysts to combine the advantages features of both homogeneous (catalyst modulation) and heterogeneous (catalyst recycling) catalysis. Functionalized germylalkenes, and germylalkanes have application in organic synthesis and materials chemistry but synthetic routes to such synthons have not been fully explored. Metal catalyzed hydrogermylation reactions can produce such synthons but very limited number of reports have appeared in literature. More over, in limited examples available, most of the reactions afford mixture of possible isomers and are carried out with activated hydrogermanes or alkynes. To the best of knowledge, systematic studies of metal catalyzed hydrogermylation reactions of functional alkynes are not known.<br/>In this communication, we disclose first example of Pt-nanocluster catalyzed, mild, one pot, high yielding, stereoselective hydrogermylation reaction. In addition, we also present preliminary studies of the nature of recyclable nanocluster catalysts <i>during the catalysis</i>.
