Substituted dimethyl and diethyl 4-(phenylethynyl)-2,6-pyridinedicarboxylates were prepared by coupling reactions between dialkyl 4-halo-2,6-pyridinedicarboxylates and terminal arylacetylenes in the presence of an organopalladium catalyst and copper(I) iodide in a suitable solvent system.The terminal acetylenes needed in this work were synthesized from the corresponding aryl halides using either (trimethylsilyl)acetylene or 2-methyl-3-butyn-2-ol followed by deprotection of the triple bond, depending on the nature of the compound in question.
