Abstract

The reaction of a range of quinones 3 with malononitrile in the presence of titanium tetrachloridalpyridine yields dicyanoquinomethides 4, which on reaction with NJP-bis (trimethylsily1) carbodiimide are converted into the mrreaponding~, 7, 7- tricyanoquinomehnimines 6. The solution electrochemical redox properties of compounds 6 have been studied by cyclic voltammetry, they are strong acceptors which readily form ...
