Conclusions
-
1.
The metallation process dominates in reaction of (C2H5)3GeLi with phenoxyacetylene, leading to C6H5OC=CLi. Addition at the acetylene bond proceeds nonregiospecifically with formation of α- and cisβ-adducts.
-
2.
Addition of (C2H5)3GeH to phenoxyacetylene under the effect of Spaier catalyst leads to a mixture of α-, cis-β-, and trans-β-adducts.
