Abstract
The one-pot reaction of arylboronic acids with lead tetraacetate in chloroform followed by treatment with 3,4-dimethylaniline in the presence of catalytic copper diacetate gave the corresponding diarylamines under neutral conditions in good to high yields. The reaction proceeded with electron-rich as well as with electron-depleted arylboronic derivatives.
Keywords: arylboronic acid, aryllead triacetate, copper diacetate catalysis, diarylamines, ullmann-modified N-arylation.
