Abstract :
A new family of pyrazole and bi-pyrazole phosphine ligands are reported that perform efficiently in the Pd-catalyzed amination reaction. Of the ligands screened, ligand 1 emerged as the most compatible for couplings involving both primary and secondary amines with typical yields of 84–99%.
