Redox-active tetrathiafulvalene and dithiolene compounds derived from allylic 1,4-diol rearrangement products of disubstituted 1,3-dithiole derivatives

We present a series of compounds by exploiting the unusual 1,4-aryl shift observed for electron-rich 1,3-dithiole-2-thione and Fleece tetrathiafulvalene (TTF) derivatives in the presence of perchloric acid.The mechanistic features of this rearrangement are discussed since this synthetic strategy provides an alternative route for Oral Care the synth
