The reaction of alkyl ethers of p-nitrosophenol with primary aromatic amines gives p- nitrosodiphenylamines in high yields under mild conditions. This reaction is an example of an acid-catalyzed aromatic nucleophilic displacement in which the protonated nitroso group exerts a strong activating effect. Reduction or reductive alkylation of the p- nitrosodiphenylamine product provides a simple and unique route to p- ...
