Abstract

Abstract: A directed heterogeneous C−H activation/halogenation reaction catalyzed by readily synthesized Pd@MOF nanocatalysts was developed. The heterogeneous Pd catalysts used were a novel and environmentally benign Fe‐based metal–organic framework (MOF) (Pd@MIL‐88B‐NH2 (Fe)) and the previously developed Pd@MIL‐101‐NH2 (Cr). Very high conversions and selectivities were achieved under very mild reaction conditions and in short reaction times. A wide variety of directing groups, halogen sources, and substitution patterns were well tolerated, and valuable polyhalogenated compounds were synthesized in a controlled manner. The synthesis of the Pd‐functionalized Fe‐based MOF and the recyclability of the two catalysts are also presented.
