chlorination of phenol derivatives using catalytic amounts of palladium acetate that is amenable to the late-stage chlorination of diflufenican and estrone. The 2-pyridine group allows for a highly efficient palladium-catalyzed chlorination and sequential ortho C–H functionalization reaction of phenol derivatives to produce a variety of symmetrical and unsymmetrical 2,4,6-trisubstituted phenols.
我们已经开发了一种使用催化量的乙酸钯进行苯酚衍生物辅助CH-H氯化的方案,该方案适用于二氟苯醚和雌酮的后期氯化。2-吡啶基允许高效的钯催化氯化和酚衍生物的顺序邻位C-H官能化反应,生成各种对称和不对称的2,4,6-三取代酚。
