Co-N 2 P 2 single-atom catalysts enable efficient -alkylation of aromatic ketones A molecular-to-atomic transformation of Co(PPh 3 ) 2 Cl 2 on a covalent triazine polymer through carbonization yields Co-N 2 P 2 single-atom sites on carbon matrix.The synergistic P/N coordination fine-tunes the Co electronic structure, enabling highly efficient -alkylation of aromatic ketones.
