✦ Synopsis

Multistep Reversible Redox Systems, LVIII^[1]^. – 2,5‐Bis(cyanoimino)‐2,5‐dihydrothieno[3,2‐b]thiophenes – a New Acceptor Type: Synthesis and Common Properties

The synthesis of a variety of substituted 2,5‐bis(cyanoimino)‐2,5‐dihydrothieno[3,2‐b]thiophenes (4) and the corresponding diones (5) is described. Different substituents on the acceptors 4 and 5 allow the redox potentials of these reversible two‐step redox systems to be varied over a wide range.
