产品说明

一般描述

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。

应用

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]
