ChemInform Abstract: Consecutive One-Pot Sonogashira-Glaser Coupling Sequence - Direct Preparation of Symmetrical Diynes by Sequential Pd/Cu Catalysis

Sonogashira cross coupling of (het)aryl iodides (I) and (IV) with trimethylsilylacetylene (II) is successfully combined with Glaser coupling using air as oxidant to give symmetrical diaryldiacetylenes (III) and (V), resp., in a two‐step one‐pot sequence.
