Production of 11,11,12,12-Tetracyano-9,10-anthraquinodimethane and derivatives thereof.

摘要

11,11,12,12-Tetracyano-9,10-anthraquinodimethane compounds useful as semiconductors and which have the general formula (I)
<CHEM>
in which Z1, Z4, Z5 and Z8 independently represent hydrogen, chlorine, hydroxy or amino and Z2, Z3, Z6 and Z7 independently represent hydrogen, halogen, alkyl which has 1 to 8 carbon atoms, phenyl, alkylphenyl whose alkyl group has 1 or 2 carbon atoms, hydroxyalkyl which has 1 to 8 carbon atoms, carboxyalkyl whose alkyl group has 1 to 8 carbon atoms, hydroxy, amino, or carboxyl, are prepared by introducing dicyanomethyl groups into an anthracene compound of the general formula (II) at the 9- and 10-positions
<CHEM>
in which Z1 to Z8 have the same meaning as above, and dehydrogenating the dicyanomethyl groups.
