1. In contrast to phenylacetylene, which reacts with Et3GeLi to give predominantly the cis- and trans-β-adducts, metalation predominates when the reaction is run with phenylthioacetylene, which leads to PhSC≡CLi. 2. When catalyzed by Speier catalyst, the addition of Et3GeH to phenyl- and phenylthioacetylene is neither region or stereospecific. The gem and cis-adducts, 2-triethylgermyl-3-phenoxy-1-propene and 1-triethylgermyl-3-phenoxy-1-propene, are formed in the case of phenyl propargyl ether.
