Room-temperature palladium-catalyzed amination of aryl bromides and chlorides and extended scope of aromatic C-N bond formation with a commercial ligand

The reactions of aryl bromides with amines occurs at room temperature when using Pd(0) and P(t-Bu)₃ in a 1:1 ratio, and the reactions of aryl chlorides occur at room temperature or 70 °C. The arylation of indoles and the new arylation of carbamates also occur when using P(t-Bu)₃ as ligand.
