General description
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。
Application
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]

Reaction of alkaline earth metal salts with diphenylphosphinic acid in dimethylformamide solvent afforded four coordination polymers: [Mg3(O2PPh2)6(DMF)2]·2DMF (I), [Ca(O2PPh2)2(DMF)2] (II), [Sr(O2PPh2)2(DMF)2] (III) and [Ba(O2PPh2)2(DMF)2] (IV) (where DMF is N,N-dimethylformamide). Single-crystal X-ray diffraction revealed that all four compounds produce linear chain
