AbstractAn effective and facile method for preparation of partially fluorinated aromatics via Nickel catalyzed, chelation‐assisted ortho selective hydrodefluorination of polyfluoroarnes with triethylsilane has been developed, in which N‐containing heterocycles were used as directing groups. The advantage of this protocol is its simple catalytic system with use of inexpensive and readily available NiCl2·6H2O as a catalyst.
Palladium-Catalyzed<i>Ortho</i>-Selective CF Activation of Polyfluoroarenes with Triethylsilane: A Facile Access to Partially Fluorinated Aromatics
PdF: A simple catalytic system, broad substrate scope, and high versatility provide a useful and facileaccess to partiallyfluorinatedaromatics (see scheme). Tuning the reaction conditions enables a diverse range of product structures to be prepared.
