The catalytic influence of clays on Bamberger rearrangement : unexpected formation of p-nitrosodiphenyl amine from N-phenylhydroxylamine
The microenvironment of montmorillonite K 10 clay and its various cation-exchanged forms, promote the formation of an unexpected product, p-nitrosodiphenyl amine, from N-phenylhydroxylamine rather than the typical Bamberger products, aminophenols. A plausible mechanism for the unusual formation of p-nitrosodiphenyl amine is proposed.
