膦 磷化氢分子中部分或全部氢原子为烃基取代的三价有机磷化合物。可分为一级膦 RPH2、二级膦R2PH和三级膦 R3P三类。膦有恶臭并有毒性。其化学特性与磷原子的孤对电子密切有关，不少性质与胺相似，具有亲核试剂和碱的性能。由于膦原子具有较大的离子半径和较低的电负性，过渡态的空间阻碍对它影响较小，膦的亲核性大于相应的氮化合物。一级膦和二级膦的碱性低于相应的氮化合物，这是由于磷原子孤对电子的轨道有较大的s特性，而氮原子的孤对电子为sp3轨道，易与质子结合。此外，膦质子化过程中溶剂化效应较弱。由于磷原子的价电子层能增至10个电子，使这类三价磷化合物具有亲电、双亲和双烯亲和性等特性。 膦的很多反应是以形成很强的磷酰键(P＝O)为推动力的。三级膦易被空气氧化为氧化三烷基膦，一级膦如甲基膦 MePH2在空气中能自燃；三苯基膦在空气中稳定,但能被氧化剂氧化。 对称的三烷基膦特别是三苯基膦是很好的配位体，易与过渡金属形成磷金属键，这类络合物溶于有机溶剂，可作为均相催化剂,膦与金属络合的性质决定于σ键、π键及空间阻碍。 对称和不对称的烷基膦可由下述反应制备： PX3+3RMgX─→R3P+3MgX2 RPX2+2R′MgX─→RR勶P+2MgX2 R2PX+R"MgX─→R2R"P+MgX2
