摘要
Palladium-catalyzed aminations of bulky aryl halides such as meso-bromoporphyrins and 9-haloanthracenes with diarylamines provided efficient syntheses of meso-aminoporphyrins and 9-aminoanthracenes. Commercially available and air-stable Pd-PEPPSI complexes that have N-heterocyclic carbene (NHC) as ligands have the highest catalytic activities. The scope of diarylamines is wide enough to use diphenylamine, phenoxazine, phenothiazine, 9,10-dihydroacrydine, and carbazole.
