Design and Synthesis of Multipurpose Derivatives for N‐Hydroxyimide and NHPI‐based Catalysis Applications**

Abstract Bi‐ and tricyclic derivatives 1 a and 2 a (Scheme 2) combining the catalytic N‐hydroxyimide NO−H unit with the imidazole moiety were designed as multipurpose derivatives and proposed as chemical tools for achieving improved homogeneous and heterogeneous aerobic oxidation catalysis. BDE tunability, formation of a ZIF and of imidazolium ionic‐liquid‐like materials were obtained for N‐hydroxyphthalimide (NHPI)‐based 2 a and here described.
