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.
衍生自dppf的镍络合物以及NaO t -Bu作为碱,可实现富挑战性的氨基磺酸氨基酯的胺化反应。以rac -BINAP为配体的新型钯催化的咪唑基磺酸盐胺化反应观察到官能团耐受性提高。
