应用
PAd-DalPhos is a versatile air stable pre-catalyst for C(sp2)-N coupling. It catalyzes N-arylation of amides with (hetero)aryl (pseudo)halide. It can also be used in the synthesis of unsymmetrical 1,3-di(hetero)aryl-1H-indazoles from hydrazine, o-chloro (hetero)benzophenones and (hetero)aryl bromides.

Palladium-catalysed C(sp(2))-N cross-coupling (that is, Buchwald-Hartwig amination) is employed widely in synthetic chemistry, including in the pharmaceutical industry, for the synthesis of (hetero)aniline derivatives. However, the cost and relative scarcity of palladium provides motivation for the development of alternative, more
