Enantioselective arylation of secondary β-C(sp3)–H bonds of 8-aminoquinoline amides was realized with a palladium catalyst. Chiral phosphoric amides and acids were used for the first time to control the stereoselectivity at the C–H bond cleavage step in the C–H activation reactions.

Abstract
A palladium-catalyzed enantioselective CH arylation of N-(o-bromoaryl)-diarylphosphinic amides is described for the synthesis of phosphorus compounds bearing a P-stereogenic center. The method provides good enantioselectivities and high yields. The products were readily transformed into P-chiral biphenyl monophosphine ligands.

Palladium-catalyzed asymmetric 1,6-addition of diarylphosphines to electron-deficient dienes was developed through rational selection of electron-withdrawing groups on the dienes. Various chiral allylic phosphine derivatives were synthesized in good yields with high enantioselectivity (up to 96% ee).

A series of bidentate monoanionic nitrogen ligands were designed and applied in the Pd-catalyzed oxidative Heck reaction of arenes with alkenes. Significant ligand-accelerated effects were observed, and direct C–H functionalized products were formed in high yields with meta-selectivity.

A Ag-mediated C–H/P–H functionalization reaction of arylphosphine oxides with internal alkynes was described for the direct preparation of benzo[b]phosphole oxides with a high yield. An unusual aryl migration on the P-atom derived from a C–P bond cleavage and a new C–P bond formation was also observed and demonstrated to proceed via the radical process.
