A fused donor-acceptor system based on an extended tetrathiafulvalene and a ruthenium complex of dipyridoquinoxaline.

An application of the Horner−Wadsworth−Emmons reaction carried out on a ruthenium compound as the electrophilic precursor is described for the synthesis of fused donor−acceptor system 1 based on an extended tetrathiafulvalene and a ruthenium complex of dipyridoquinoxaline units.
