✦ Synopsis
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.
