摘要：

Aryl bromides were converted to diaryl ethers with sodium aryl oxides in the presence of catalytic amounts of Pd(DBA)(2) and DPPF. Isolated yields of over 90% were achieved in reactions with electron deficient aryl bromides and electron rich sodium aryl oxides. Electron poor DPPF derivatives led to increased reaction yields.
