Nitrosobenzene, CjHsNO, which is obtained by the oxidation of phenylhydroxylamine, and p>nitrosodimethylaniline, p-(CH3)2NCjH4NO, which is easily prepared by the nitrosation of dimethylaniline, are fairly specific oxidizing agents for the preparation of aromatic aldehydes from benzyl halides or tosylates and of a-dicarbonyl compounds from from a-halo ketones [984, 985]. Also, a methylene group flanked by two carbonyls can be oxidized to a carbonyl group by nitrosodimethylaniline [986]. Pyridine is frequently used to form quaternary pyridinium salts from reactive halides prior to their oxidation to aromatic aldehydes, a-ketoaldehydes, or a-diketones [984] (equations 22 and 23).

Whilst 5-amino-2-chloropyridine reacted readily with nitrosobenzene in acetic acid, giving 2-chloro-5-phenylazopyridine387d 2- and 4-aminopyridine did not react with j -nitrosodimethylaniline under these conditions389. The failure has been attributed to protonation of both the aminopyridines and the nitroso compound and indeed 2-, 3- and 4-aminopyridines4 7 and their...
