Abstract It was found that introduction of only 0.03 mol % Ag(I) into the framework of Cu 3 (BTC) 2 ⋅ xH 2 O in maghemite anchored CuBTC activated the inert CuBTC astonishingly to exhibit unexpected high catalytic activity for C−Cl activation in coupling of chloroarenes with phenols without the use of expensive ligands. This is the first application of mixed‐metal MOFs in the C−X activation. Putting reusability and activity together, a TON over 15000 was obtained which is the highest TON compared with all its precedents even better than the results by Pd catalysts.
