主 题：lignin zinc single atom catalyst N-doped porous carbon α-alkylation borrowing hydrogen
摘 要：A green and scalable strategy has been developed for the synthesis of lignin-derived Zn single atom/N-codoped porous carbon(LCN@Zn-SAC)containing similar ZnNx sites with carbonic *** catalyst exhibits superior activity on theα-alkylation of ketones with alcohols via borrowing hydrogen strategy(TON up to 15 h^(−1))than most of previously reported *** dehydrogenation of benzyl alcohol is the rate-determining step based on kinetic experiment *** to experimental and theoretical calculation results,Zn electron density is inversely proportional to reaction energy barriers,because Zn sites with less positive charge(ZnN_(4) and ZnN_(3)C)in Zn-SACs display better borrowing hydrogen ability than other Zn ***,this catalyst can be recycled by simple centrifugation,which can be reused at least 8 runs with no obvious lose in *** the best of our knowledge,this is the first example of non-noble metal-SAC-catalyzedα-alkylation via borrowing hydrogen strategy.
