directing ligand derived from 2,1,3-benzoselenadiazole (BSeD) was designed and synthesized. It exhibited high regioselectivity in the catalytic activation of unactivated C(sp3)-H bonds with aryl iodides in the presence of palladium catalyst in yields up to 94%.
设计并合成了衍生自2,1,3-苯并硒基二唑(BSeD)的改性双齿定向配体。在钯催化剂的存在下,它在未活化的C(sp 3)-H键与芳基碘化物的催化活化中表现出很高的区域选择性,产率高达94%。
