二苯基膦酸 (DPPA，hdpp) 是一种有机膦酸化合物。它在钯催化体系中用作反应性阻燃剂和促进剂。采用热重分析 (TGA) 法研究了二苯甲酮 (DPPA) 的热降解。在二甲基甲酰胺溶剂中，DPPA 与硝酸镉反应生成一维配位聚合物链聚 [[双（二甲基甲酰胺-κO）镉 (II)]-双（μ-二苯基膦酸-κ (2)O:O′）]。已有促进硝基苯和苯胺羰基化合成二苯基脲的方法的报告。邻位 锂化 DPPA 可通过亲电捕获和联苯-2,2′ 形成单 邻位 功能化衍生物-铜催化偶联苯基膦酸。 二苯基膦酸是合成有机膦化合物的重要起始原料。二苯基次膦酸可在二甲基甲酰胺 (DMF) 溶剂中通过与碱土金属盐反应制备配位聚合物 ： • [Mg3(O2PPh2)6(DMF)2]·2DMF • [Ca (O 2 PPh 2 ) 2 (DMF) 2 ] • [Sr (O 2 PPh 2 ) 2 (DMF) 2 ] • [Ba(O2PPh2)2(DMF)2] 通过与 LAlH 2 (L = HC (CMeNAr) 2 ，Ar = 2,6-iPr 2 C 6 H 3 ) 反应，可用于合成具有 Al-O-X (X = Si，P，C) 基序的化合物。[N719 染料敏化的纳米 TiO 2 可作为染料敏化太阳能电池 (DSC) 的新型共吸附剂。该化合物可用于芳香膦酸的合成。 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(dimethylformamide-κO)cadmium(II)]-bis(μ-diphenylphosphinato-κ(2)O:O′)].[1] It has been repoted to promote the carbonylation of nitrobenzene and aniline to diphenylurea. Ortho-lithiated DPPA can form mono ortho-functionalized derivatives by electrophilic trapping and biphenyl-2,2′-diylbis(phenylphosphinic acid) by copper catalyzed coupling. 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
