In 2022,Dahiya, Amit; Schoenebeck, Franziska published an article in Organic Letters. The title of the article was ãDirect C-H Dehydrogenative Germylation of Terminal Alkynes with Hydrogermanesã?Computed Properties of C7H5N The author mentioned the following in the article:
A direct C(sp)-H germylation of terminal alkynes with tri-Et Ge hydride is reported. The method is operationally simple and makes use of B(C6F5)3 catalysis in combination with 2,6-lutidine as an organic base. Exclusive selectivity for dehydrogenative germylation of the alkyne over the competing hydrogermylation is observed The results came from multiple reactions, including the reaction of 4-Ethynylpyridine(cas: 2510-22-7Computed Properties of C7H5N)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Computed Properties of C7H5N
