The reaction of p-nitroaniline with aryl isocyanates (2a-2d) in the presence of potassium carbonate leads to 4-nitrophenylamines (4a-4d).The reaction of p-nitroaniline with n-propyl isocyanate yields 4,4'-dinitrodiphenyl amine (10). o-Nitroaniline reacts with the isocyanates (2a and 2b) to yield 2-nitrodiphenyl amines (11a and 11b).The reaction of p-nitroaniline with phenyl isothiocyanate yields the guanidine (12) besides 4-nitrodiphenylamine (4a) and N,N'-diphenylthiourea.
