AminesQ 0120 Arylation of Diarylamines Catalyzed by Ni(II)—PPh3 System. — Bromomagne-

sium diarylamides are coupled with aryl bromides and iodides in the presence of nickel(II)-catalyst to give triarylamines. Double cross-coupling employing diiodo- or dibromoarenes also proceeds in good yields. The method represents an alternative to Pd-catalyzed or Cu-mediated methods. — (CHEN, C.; YANG*, L.-M.; Org.
