We report on the stepwise homologation of the ethynyl substituted pyridine, 2,2′-bipyridine, and 2,2′:6′,6″-terpyridine with bromoethynyl(triethyl)silane using the Chodkiewicz method. Chelating ligands bearing one or two triethylsilylbutadiyne, one or two triethylsilylhexatriyne subunits have been synthesized and fully characterized.
