Abstract
Monolithiation of tetrathiafulvalene (2-(1,3-dithiol-2-ylidene)-1,3-dithiole, TTF) followed by reaction with the appropriate p-toluenesulphonyl halide yields monochloro-, monobromo- and monoiodo-TTF (34-48 % yield); tetrachloro-TTF is obtained in 30 % yield by tetralithiation of TTF followed by addition of p-toluenesulphonyl chloride. Cyclic voltammetric data establish that the oxidation potential of TTF is significantly increased upon halogenation.Keywords
