Abstract
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.
Key words
amination - palladium - cross-coupling - organosulfur compounds
