Bio‐MOF‐11 Derived Amorphous Cobalt Hollow Nanospheres to Access Bioactive Quinazolinone Scaffolds and Aromatic Amines

Abstract A facile synthetic strategy is reported to afford bioactive quinazolinones and aromatic amines by employing amorphous cobalt hollow nanospheres (Co HNS) derived from a Bio‐MOF, cobalt adeninate, as a catalyst. Modulated electron states of the amorphous cobalt with a high concentration of surficial active sites and Co–N sites enhance the intrinsic catalytic activity while the support, activated carbon, facilitates the formation of hollow structure.
