Synthetically useful 1,3-dithiol-2-ylphosphonate esters 3 can be prepared in one step, and in good yield (up to 75%), from the corresponding 1,3-dithiole-2-thiones 1, simply by heating in the presence of a trialkyl phosphite at high dilution.
A series of tetraalkylthio substituted tetrathiafulvalenes (TTCn-TTF) was prepared. The syntheses, molecular and crystal structures, and physical properties of TTCn-TTF reveal marked differences from those of BEDT-TTF. The conformational change of TTC1-TTF molecule on the formation of chargetransfercomplexes and the mode of the S…S contacts are described in connection with those of BEDT-TTF compounds
