Beschreibungen/Notizen

• Mono‐, di‐, and tetraalkynylated selenophenes were prepared by site‐selective Sonogashira reactions of tetrabromoselenophene. Aryl‐, alkyl‐, and trimethylsilylacetylenes were suitable substrates for this procedure. The first attack occurred regioselectively at C‐2 and C‐5. In addition, differently diarylated dialkynylselenophenes were prepared using site‐selective Suzuki and Sonogashira reactions. Mono‐, di‐, and tetraalkynylated selenophenes can be ontained by site‐selective Sonogashira reactions of tetrabromoselenophene. Aryl‐, alkyl‐, and trimethylsilylacetylenes are suitable starting materials. Differently diarylated dialkynylselenophenes can be synthesized by site‐selective Suzuki and Sonogashira reactions.
