Halogenated TTF derivatives, especially iodinated ones, are important compounds as intermediates for further TTF derivatization, as well as for their intrinsic value as donors with an increased tendency to participate in intermolecular interactions compared to TTF, in the charge transfer (CT) complexes and ion-radical salts derived from them1. Our previous work has shown that stepwise bromination of lithiated TTF can give rise exclusively to 2,3-dibromo-TTF in moderate yields2, out of the three possible dibromo-TTF isomers. The stacking mode (Figure 1) shows both Br...Br (3.669Å) and Br...S (3.646Å) interactions.
