Catalytic Synthesis of Triarylamines

Tarasievich,Mikhalevskaya,Kozlov

, p. 1100 - 1102 (2007/10/03)

Condensation along Ullman reaction in the presence of copper catalysts was carried out with para-substituted arylamines and p-iodotoluene to yield the corresponding triarylamines. For preparation of diarylamines was used dehydrogenation of N-cycloalkylanilines and azomethines; diarylamines were obtained through dehydroamination of cycloaliphatic alcohols with anilines.
