General description

Yu Fluorination Ligand is widely employed for the chemoselective functionalization of sp2- and sp3 C-H bonds.

Application

The Yu Fluorination Ligand in tandem with Selectfluor(R) (Aldrich 439479) under palladium catalysis can promote direct fluorination of C(sp3)-H bonds stereoselectively. Yu and coworkers have displayed this on amino acid derivatives with directing group assistance from the Yu-Wasa Auxiliary (Aldrich 791806).
