| Application: | Diphenylphosphinic acid is an important starting material for the synthesis of organophosphinic compounds. Diphenylphosphinic acid may be used for the preparation of coordination polymers, via reaction with alkaline earth metal salts in dimethylformamide (DMF) solvent: • [Mg3(O2PPh2)6(DMF)2]·2DMF • [Ca(O2PPh2)2(DMF)2] • [Sr(O2PPh2)2(DMF)2] • [Ba(O2PPh2)2(DMF)2] It may be used for the synthesis of compounds with the Al-O-X (X = Si, P, C) motif, via reaction with LAlH2 (L = HC(CMeNAr)2, Ar = 2,6-iPr2C6H3). It may be employed as a novel co-adsorbent in dye-sensitized solar cells (DSCs) based on nanocrystalline TiO2 sensitized with N719 dye. It may be used in the synthesis of arylindium phosphinate. |
| General description: | Diphenylphosphinic acid (DPPA, hdpp) is an organophosphinic acid compound. It finds application as a reactive flame-retardant and promoter for palladium catalytic systems. Thermal degradation of DPPA has been studied by thermogravimetric analysis (TGA) method. DPPA reacts with cadmium nitrate in dimethylformamide solvent to afford the one-dimensional coordination polymer catena-poly[[bis(dimethyl |
