products. Here, we show that solid-state high-temperature ball-milling conditions facilitate a palladium-catalyzed cross-coupling with polyfluorinated arylboronic acids and pinacol esters employing a simple catalytic system in the absence of any stoichiometric additives. This reaction exhibits a broad substrate scope and can be carried out in air, and the use of large amounts of dry and degassed organic solvents

Pd-catalyzed decarboxylative cross coupling of potassiumpolyfluorobenzoates with arylbromides, chlorides, and triflates is achieved by using diglyme as the solvent. The reaction is useful for synthesis of polyfluorobiaryls from readily accessible and nonvolatile polyfluorobenzoate salts. Unlike the Cu-catalyzed decarboxylation cross coupling where oxidative addition is the rate-limiting step, in
Ni‐catalyzed decarboxylative cross‐coupling of potassium polyfluorobenzoates with unactivated phenol and phenylmethanol derivatives is described. This novel transformation provides a practical and efficient protocol towards the synthesis of important polyfluorobiaryls and polyfluorinated diarylmethanes, and greatly enlarges the range of electrophiles utilized in decarboxylative coupling. Remarkably, preliminary

efficient tandem route for the synthesis of polyfluoroterphenyl derivatives has been developed. The target compounds were obtained in moderate to good yields by a Pd(OAc)2‐catalyzed three‐component coupling reaction involving palladium‐catalyzed direct CH activation of perfluoroarenes. This in turn will set the stage for a wide application of this useful reaction for the synthesis of fluorinated liquid crystal
