General description

Crystallographic analysis of 6,11-dihydroxy-5,12-naphthacenedione has been reported. Study indicates the presence of (3Z,3′Z)-3,3′-(ethane-1,2-diylidene)bis[isobenzofuran-1(3H)-one] as impurity.

Application

6,11-Dihydroxy-5,12-naphthacenedione was used in the synthesis of a tetracene derivative, 5,6,11,12-tetrachlorotetracene. It was also used for the synthesis of (3Z,3′Z)-3,3′-(ethane-1,2-diylidene)bis[isobenzofuran-1(3H)-one]. It may be used for the following studies:
  • Synthesis of self-assembled, chair-shaped dirhenium(I) macrocyclic compounds.
  • Synthesis of half-sandwich Ir, Rh-based organometallic molecular boxes.
  • As ligand for the synthesis of supramolecular coordination complexes (SCCs).
