Herein, we present a homo-binuclear macrocyclic complex-mediated strategy for constructing cobalt-based diatomic catalysts, in which dioxygen-bridged cobalt dual-atom sites (Co–O<sub>2</sub>–Co) are uniformly embedded within hierarchically porous carbon nanospheres (denoted Co–O<sub>2</sub>–Co/HPCN) to promote efficient oxygen reduction reaction (ORR) catalysis. Notably, the hierarchically porous architecture, derived via a sacrificial-template approach, provides abundant and interconnected micro/mesopores that effectively confine the cobalt binuclear complex precursor, ensuring the atomic dispersion and structural integrity of Co–O<sub>2</sub>–Co sites. Importantly, the unique Co–O<sub>2</sub>–Co coordination motif stabilizes the *OOH intermediate through side-on bridge adsorption, thereby facilitating O–O bond cleavage and breaking the conventional *OOH–*OH scaling relationship. Benefiting from this synergistic structural and electronic modulation, Co–O<sub>2</sub>–Co/HPCN achieves an onset potential of 1.016 V and a half-wave potential of 0.916 V, surpassing commercial Pt/C catalysts. Moreover, Co–O<sub>2</sub>–Co/HPCN exhibits high power density and outstanding durability in both aqueous and flexible quasi-solid-state zinc-air batteries, underscoring its promise for next-generation energy technologies.

Our innovative strategy leverages P(III)-directed C–H activation, which entails the direct arylation of triarylphosphines with enantiomerically enriched PCP bromides.

These <em>in situ</em> modified chiral ligands have exhibited exceptional efficacy in Pd-catalyzed asymmetric allylic alkylation and Suzuki-Miyaura coupling, underscoring their potential for widespread applications in asymmetric catalysis.
