Derivatizing immobilization methods for TEMPO radicals in metal–organic frameworks: Toward efficient aerobic oxidation and sequential reactions

Bulletin of the Korean Chemical Society, EarlyView.
Covalent attachment of TEMPO radicals to Zr‐based metal–organic frameworks (MOFs) was achieved by diversifying linker structures, enabling efficient aerobic oxidation of secondary alcohols. The modified MOFs facilitated sequential reactions, including isoxazole synthesis via aerobic oxidation and cycloaddition, demonstrating their versatility and ...
