The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this
Bulky diadamantyl aryl phoshine ligands were synthesized and utilized in Buchwald‐Hartwig couplingreactions of sterically demanding ortho‐substituted arylchlorides. The ligands also showed enhanced catalytic activity in the coupling of tosyl hydrazones and aryl halides.

methoxy groups has been designed for Pd-catalyzed Buchwald-Hartwigamination. It is worth noting that this new catalyst system was found to be highly effective in facilitating the cross-coupling reaction even at parts per million levels of palladium catalyst. A wide range of arylchlorides as well as amine nucleophiles were successfully employed for the aromatic C–N bond-forming reaction. Remarkably
