- Palladium-Catalyzed Amination of Aryl Sulfides and Sulfoxides with Azaarylamines of Poor Nucleophilicity
-
The amination of aryl sulfides and sulfoxides with azaarylamines is investigated using a palladium-N-heterocyclic carbene (NHC) complex. Because azaarylamines are less nucleophilic than anilines, more reactive diaryl sulfides and sulfoxides are found to be suitable coupling partners that liberate better leaving arenethiolate or arenesulfenate anions, instead of aryl methyl sulfides as reported previously.

- LIGANDS FOR TRANSITION-METAL-CATALYZED CROSS-COUPLINGS, AND METHODS OF USE THEREOF
-
Ligands for transition metals are disclosed herein, which may be used in various transition-metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The disclosed methods provide improvements in many features of the transition-metal-catalyzed reactions, including the range of suitable substrates, number of catalyst turnovers, reaction conditions, and efficiency. For example, improvements have been realized in transition-metal-catalyzed cross-coupling reactions.
