aromatic amines with aromatic aryl iodides. Full spectroscopic details are reported. Solutions of 1,3,5-tris(diarylamino)benzene derivatives in deuterated chloroform undergo hydrogen–deuterium exchange on the central ring and readily turn green owing to partial oxidation by traces of dissolved oxygen. The green colour is quenched by the addition of ascorbic acid. The solutions are more stable in chloroform
