Palladium-catalyzed synthesis of alkynylated 1,4: 5,8:11,14:15,18-tetrasulfido(20)annulenes

The syntheses of tetraalkynylated tetrasulfido[20]annulenes 2a−d are described. Treatment of the corresponding brominated tetrasulfido[20]annulene 5a (easily available by McMurry coupling of the brominated 2,2′-bithiophene-5,5′-dicarbaldehydes, 3a) with various acetylenes in the presence of Pd(II) a...
