Pd(OAc)2-Catalyzed Oxidative C−H/C−H Cross-Coupling of Electron-Deficient Polyfluoroarenes with Simple Arenes
摘要:
Pd(OAc)(2)-catalyzed intermolecular C-H/C-H cross-coupling reactions between electron-deficient polyfluoroarenes and simple arenes for the synthesis of fluorinated biaryls have been developed. Deuterium-labeling experiments suggested that C-H bond cleavage of the simple arenes rather than the polyfluoroarenes is involved in the rate-limiting step.

combination of copper iodide and phenanthroline as the ligand is an efficientcatalyst for Suzuki‐Miyaura cross‐coupling of highly fluorinated boronate esters (aryl−Bpin) with aryl iodides and bromides to generate fluorinated biaryls in good to excellent yields. This method represents a nice alternative to traditional cross‐coupling methods which require palladiumcatalysts and stoichiometric amounts of

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.

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

The most efficient method to construct biaryls is the direct dehydrogenative cross-coupling of two different aromatic rings. Such an ideal cross arylation starting from distinct polyfluoroarenes and simple arenes was presented. The selectivity of the cross-coupling was controlled by both of the electronic property of fluoroarenes and steric hindrance of simple arenes. Diisopropyl sulfide was essential to promote the efficacy.
