Thionophosphine Sulfides. II. Preparation and Chlorination of Phosphonodithioic Acids^1a

Crystal and Molecular Structures of trans-Nickel(II)-bis[(O-propyln)-(p-methoxyphenyl)dithiophosphonate]

“…4 A 4.6 g (16.70 mmol) sample of the ligand was dissolved in 100 mL of glacial acetic acid; to this solution, 83.5 mL of a Ni(II) acetate solution in acetic acid was added dropwise in about 30 min. The title compound crystallized out directly from the reaction mixture.…”

Pivotal Neighboring‐Group Participation in Substitution versus Elimination Reactions – Computational Evidence for Ion Pairs in the Thionation of Alcohols with Lawesson's Reagent

“…On the other hand, the thionation of alcohols with LR is not a general reaction. The reaction of primary alcohols and phenols does not provide the corresponding thiols but phosphonodithioic acids, which were already prepared 20 years previously through the reactions between alcohols and phosphorus pentasulfide . Alcohols bearing a phenyl ring at the alcoholic carbon atom undergo thionation more readily, although a clear competition occurs with the corresponding elimination reaction .…”

Synthesis and Characterization of Zn(II) and Cd(II) Complexes with Bisdithiophosphonates

“…The compounds derived from reactions of organophosphorodithio ligands such as dithiophosphonate [1][2][3][4][5][6][7][8][9][10], dithiophosphinato [11,12], and dithiophosphate [13][14][15][16] with transition metals, have significant properties and were efficiently used in technological and agricultural fields. For example, these ligands were used as antioxidants for lubrication oils, flotation agents for mineral ores, solvent extraction agents for metal cations, insecticides and pesticides [1,2,4].…”

“…The reactions of 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide ( A ) with alkane diols ( B ) were investigated by Sahabane et al [17]. Methylthionophosphine sulfide reacted with ethylene glycol to give O , O -(1,2-ethylene)bis(metyldithiophosphonic acid) [3]. However, the coordination chemistry of tetradentate bisdithiophosphonate ligands with metal cations and their properties remains insufficiently studied.…”
