Abstract

Photolysis of dibromobenzotrithiole (1) and tetrabromodibenzotetrathiocin (4) in CH2Cl2 produced tetrabromothianthrene (2). Compound (2) was treated with CuCN in DMF at 150°C to give tetracyanothianthrene (5). Dinuclear phthalocyanine (9) was constructed by treatment of a mixture of 5 and dioctoxyphthalonitrile (6) with lithium in n-pentanol.
