一般描述
四(三苯基膦)钯(0)（Pd(PPh3)4）是化学合成中常用的钯(0)配合物。在各种有机反应中，特别是C-C、C-N、C-O和C-杂原子交叉偶联反应，它作为催化剂起着至关重要的作用。Pd(PPh3)4广泛应用于碳-碳键形成反应，例如著名的Heck、Suzuki-Miyaura和Stille反应。这些反应涉及芳基、烷基或乙烯基卤化物与其他有机化合物偶联，产生有价值的产物。催化循环包括将有机卤化物氧化加成到钯(0)中，用合适的有机金属试剂或硼酸进行转移金属化，以及还原消除以形成所需产物。Pd(PPh3)4还用于其他多种转化，包括烯丙基取代、烯烃和炔烃的亲核加成以及环加成。
应用
- Negishi偶联反应（反应式1）, 铃木偶联反应（反应式2），Stille偶联反应（反应式3），以及Sonogashira偶联反应（反应式4），以及Buchwald-Hartwig氨基化反应（反应式5)
- 碘化乙烯的羰基化反应（反应式6)
- 芳基溴化物的还原反应（反应式7)
- 碳-锡键形成反应（反应式8）
