A protocol for the synthesis of mono- and bis-phosphanylated 1,3-dithiole-2-thiones 2 and 3 is presented. The reaction of 2 or 3 with hydrogen peroxide-urea or elemental sulfur led to the corresponding P(v) chalcogenide 1,3-dithiole-2-thiones 4-7. All compounds were characterized by 31P, 1H and 13C NMR and IR spectroscopy and elemental analyses. Additionally, compounds 3 and 4 were analysed by single-crystal X-ray diffraction analysis. The reaction of 3 with P(OEt)3 led selectively to the tetrakis-phosphanylated tetrathiafulvalene derivative IIvia a reductive C2,C2 coupling reaction. A thorough computational analysis for the mechanism of phosphite-mediated reductive dimerization of 1,3-dithiole-2-thiones was performed. This journal is
Bis- and tetrakis-(diphenylphosphino) tetrathiafulvalenes as precursors of redox-active organic-inorganic polymeric networks

Lithiation of the (Z)-, (E)-dimethyltetrathiafulvalene mixture and subsequent reaction with ClPPh2 afford (Z)- and (E)-dimethylbis(diphenylphosphino)tetrathiafulvalene which are separated by fractional recrystallization. The identity of (Z)-P2 has been ascertained by its X-ray crystal structure determination. By similar methods, tetrakis(diphenylphosphino)tetrathiafulvalene (P4) is obtained from the tetrathiafulvalene tetralithium derivative. Cyclic voltammetry experiments reveal that the new compounds oxidize reversibly in two one-electron steps to the radical cation and dication. Reaction of 0-P2 with the dinuclear complex [Rh2(NCCH3)10](BF4)4 has been investigated and found to produce the square-planar Rh(I) compound [(0-P2)2Rh][BF4]. The identity of the product has been confirmed by X-ray crystallography, FAB-MS, elemental analysis, and NMR spectroscopy. Several reactions of solvated cations were also performed, all of which appear to lead to products with 0-P2 and P4 ligands.

The synthesis, 31P NMR and electrochemical properties of a set of four tetrathiafulvalenes substituted with -PPh2 groups are described.The coordinating ability as well as the redox properties of these molecules are illustrated by several examples of complexes and cation-radical salts.
