The reaction of 4-O2NC6H4NH2 (I) with RC6H4NCO (II; R = H, 4-Me, 4-Cl, 3-Cl) in the presence of K2CO3 gave 4-O2NC6H4NHC6H4R (III). The reaction of I with PrNCO gave (4-O2NC6H4)2NH. 2-O2NC6H4NH2 reacted with II (R = H, 4-Me) to give the corresponding 2-O2NC6H4NHC6H4R. PhNCS was treated with I to give 4-O2NC6H4N:C(NHPh)2, III (R = H), and PhNHCSNHPh.
