Conclusions 1. Reaction of triethylgermyllithium with 3-phenoxy- or 3-phenylthio-1-propyne occurs principally in the direction of metallization at the acetylenic hydrogen atom. The isomeric 1-phenoxy- or 1-phenylthio-1-propynes under these conditions do not form addition products at the triple bond. In reaction with phenoxyallene the Et3Ge anion mainly attacks the terminal methylene group. 2. Hydrogermylation and hydrosilylation of these compounds takes place nonregiospecifically with formation of the α and β adducts. Phenoxyallene adds on to triethylgermane in the 1,2- and 2,3- positions.
