bidentate phosphine ligand, offering an invaluable synthesis means to construct extensive p-difluoromethylated products and difluorooxindole derivatives with significant functional fragments. Furthermore, the gram-scale reaction, broad substrate scope, excellent functional-group compatibility, late-stage difluoromethylation of pesticides, and even formal synthesis of HDAC6 inhibitors further demonstrate the
在此,在二齿膦配体的帮助下,开发了第一个用于镍催化的各种芳族胺的邻位或对位二氟甲基化的催化方案,为构建广泛的对二氟甲基化产物和具有重要功能片段的二氟羟吲哚衍生物提供了宝贵的合成方法。 . 此外,克级反应、广泛的底物范围、优异的官能团相容性、农药的后期二氟甲基化,甚至HDAC6抑制剂的正式合成进一步证明了该方法的实用性。
