衍生自 dppf 的镍配合物以及 NaOt-Bu 作为碱，可以实现具有挑战性的芳基氨基磺酸盐的胺化。在以 rac-BINAP 作为配体的新型钯催化咪唑基磺酸胺化反应中观察到改进的官能团耐受性。
A nickel complex derived from dppf, along with NaOt-Bu as the base, allowed for challenging aminations of aryl sulfamates. An improved functional group tolerance is observed in novel palladium-catalyzed aminations of imidazolylsulfonates with rac-BINAP as the ligand.
