partially fluorinated arenes. A nickel-catalyzed cross-coupling between a polyfluoroarene and an organozincreagent in the presence of POP selectively produces a monosubstitution product. Aryl and alkylzinc reagents smoothly take part in the reaction. It is speculated that monosubstitution is the result of accelerated product expulsion from the product/catalyst complex.
