Molbank, Vol. 2018, Article M987: 5,5´-Bis[5-(9-decyl-9H-carbazol-3-yl)thien-2-yl]-4H,4´H-[3,3´-bi(1,2,6-thiadiazine)]-4,4´-dione (Molbank)

Stille coupling of 5,5´-dichloro-4H,4´H-[3,3´-bi(1,2,6-thiadiazine)]-4,4´-dione (8) with 9-decyl-3-[5-(tributylstannyl)thien-2-yl]-9H-carbazole and Pd(Ph3P)2Cl2 in PhMe, at ca. 110 °C, for 2 h, gave 5,5´-bis[5-(9-decyl-9H-carbazol-3-yl)thien-2-yl]-4H,4´H-[3,3´-bi(1,2,6-thiadiazine)]-4,4´-dione (7) in 51% yield. The latter is investigated as an oligomer donor for organic photovoltaics.
