Abstract

The Bamberger rearrangement is the most convenient and economical method for the synthesis of para-aminophenols directly from nitrobenzenes, particularly on an industrial scale.' The process is normally carried out by catalytic hydrogenation in the presence of precious metal catalysts under highly acidic conditions where the intermediate has been shown to be N-phenylhydroxylamine . An interesting recent development in catalytic transfer hydrogenation (CTH) , an ...
