Transition-metal-catalyzed asymmetric C-P(III) bond formation is a direct method for the construction of P(III)-stereogenic centers; however, achieving high enantioselectivity remains challenge. Herein, an unprecedented Cu-catalyzed dynamic kinetic resolution secondary phosphine-boranes was successfully developed. This C-P(BH3) coupling reaction provided and highly enantioselective synthesis centers, enabling chiral medium-sized benzophosphine-boranes (7-10-membered cycles). A mechanism involving unusual rapid racemization has been proposed.

Migratory functionalization of C-H bonds through metal migration from carbon to under transition catalysis is a process significant academic and industrial interest. Herein, palladium-catalyzed migratory cyclization α-bromoalkene derivatives ArXCBr=CH2, in which X denotes phosphorus (P(O)R), silicon (SiR2), sulfur (SO2), (C(O)), nitrogen (NTs), or oxygen-based moiety, affording various benzoheterocyclic compounds has been developed. Mechanistic investigations have demonstrated that the reaction proceeds an unexpected cascade, with trans-1,2-palladium between sp2 carbons being key step catalytic cycle. To best our knowledge, this type not reported previously.

Due to the inherent challenges posed by linear coordination of gold(I) complexes, asymmetric gold-catalyzed processes remain challenging, particularly in atroposelective synthesis axially chiral skeletons. Except for extremely few examples intramolecular annulations, construction axial chirality via intermolecular alkyne transformation is still undeveloped. Herein, a gold/HNTf
