For copper only: The decarboxylative cross‐coupling of readily accessible and nonvolatile potassiumpolyfluorobenzoates with aryliodides and bromides using a copper catalyst provides polyfluorobiaryls and polyfluorostilbenes in excellent yields (see scheme). Mechanistic analyses are reported for the title reaction.

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

A new catalyst for the cross-coupling Suzuki–Miyaura reaction is reported. The impregnated palladium on magnetite catalyst is very easy to prepare using the standard impregnation methodology. This catalyst avoids the use of any type of expensive and difficult handle organic ligand, showing excellent yields, under mild reaction conditions, for the classical formation of biaryl compounds. The catalyst

reaction of potassium polyfluorobenzoates with aryl iodides and bromides was achieved in diglyme or DMAc at 130 or 160 °C in the presence of 10–20 mol% of a 1,10-phenanthroline-functionalized MCM-41-immobilized copper(I) complex, [MCM-41-Phen-CuI], yielding a variety of polyfluorobiaryls in good to excellent yields. This heterogeneous copper(I) complex could easily be prepared via a simple procedure

tBu3P-Coordinated2-phenylaniline-basedpalladacyclecomplex was demonstrated to be an efficient precatalyst for Pd-catalyzedcouplingreactions of arylhalides with polyfluoroarenes via C-Hactivationstrategy. The readily accessibility and easy handling nature of tBu3P- coordinated 2-aminobiphenyl-based palladacyclecomplex and the high yields of the reaction makes tBu3P-coordinated 2-aminobiphenyl-based
