Multistep, Reversible Redox Systems, XXXVI. — 11,11,12,12‐Tetracyano‐9,10‐anthraquinodimethane (TCNAQ) and its Derivatives: Synthesis and Redox Properties Title compounds 3Ba – d are synthesized from the corresponding anthraquinones and malononitrile with titanium tetrachloride/pyridine. By comparison of the potentials and semiquinone formation constants of 1B – 3B with those of the corresponding quinones 1A – 3A strong distortion of the biscyanomethylene groups in 2B and especially 3B is derived.
