Primary aryl amines reacted with aryl halides to give the secondary aryl amines by the catalysis of [Pd (dba) 2/P (t-Bu) 3] at 80° C in toluene. Secondary aryl amines reacted with 1- bromo-pyrene and 9-bromo-phenanthrene and 2, 7-dibromo-9H-fluorene to afford the OLED material of aminopyrene derivatives and aminophenanthrene derivatives and diamino-9H- fluorene type by the catalysis of [Pd (OAc) 2/P (t-Bu) 3] at 120° C in o-xylene. The product ...
