The palladium-catalyzed cross-dehydrogenative-coupling of polyfluoroarenes with alkenes or simple arenes has been developed. The approach is characterized by using atmospheric pressure of molecularoxygen as the sole oxidant, and provides a straightforward and environmentally benign route to functionalized polyfluoroarenes.

The palladium-catalyzeddirectarylation of electron-deficient arenes that contain two or more fluorine groups with arylboronic acids was realized. The key to achieving a broad substrate scope with respect to both polyfluorobenzenes and arylboronic acids is the choice of bases depending on acidities of polyfluorobenzenes.

polyfluoroarenes with readily available aryliodine(III) diacetates was developed with moderate to good yields. The process exhibited good functional tolerance with respect to methyl, methoxy, bromo, chloro, trifluoromethyl, cyano, and aldehyde groups. Mechanistic studies revealed this coupling involved in situ generation of aryl iodide from heating-promoted decomposition of aryliodine(III) diacetate, followed by

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
