General Description

Tetramethylbiphosphine disulfide is a chemical compound with the molecular formula C8H20P2S4. It is commonly used as a reagent in organic synthesis and as a ligand in coordination chemistry. It is a yellow crystalline solid with a distinctive odor and is highly reactive due to the presence of two phosphorus and sulfur atoms. Tetramethylbiphosphine disulfide is a strong reducing agent and can undergo various chemical reactions, including the formation of metal complexes and the reduction of organic compounds. It is commonly used in the pharmaceutical and agrochemical industries as a versatile building block for the synthesis of complex organic molecules. Additionally, it has potential applications in material science, catalysis, and the development of new chemical processes. Due to its reactivity and potential hazards, proper precautions should be taken when handling and storing tetramethylbiphosphine disulfide.

Ligating Properties of t-Phosphine/Arsine Sulphides and Selenides: Part VIII - Synthesis and Characterization of Mercury(II) Complexes with Some Ditertiaryphosphine Disulphides

Ditertiaryphosphine sulphides, namely, 1,1-methylene(MDPS)-, 1,2-dimethylene(EDPS)-, 1,3-trimethylene(PDPS)- and 1,4-tetramethylene(BDPS)-bis(diphenylphosphine sulphides) react with mercury(II) nitrate in acetone forming complexes of the type Hg(NO3)2.L.Tetramethyldiphosphine disulphide(TMDPS) gives 1:1 adduct with mercury(II) bromide and 3:2 adduct (metal:ligand) with mercury(II) chloride and iodide.Characterization of the complexes has been carried out on the basis of their elemental analyses, IR spectra and molar conductances in nitrobenzene.All the adducts are non-electrolytes.Complexes of TMDPS and MDPS, forming five- and six-membered rings, have been assigned chelated tetrahedral stereochemistry, while the complexes of EDPS, PDPS and BDPS have been assigned polymeric structures.
