Beckmann rearrangement in the solid state: Reaction of oxime hydrochlorides

Several ketoxime hydrochlorides undergo Beckmann rearrangement upon heating below their melting points for 5-48 h, in excellent yields (generally >70%). The absence of a reaction solvent and of by-products (except for HCl) makes for a very simple work-up. Aldoxime hydrochlorides apparently undergo dehydration to the corresponding nitriles under the above conditions. Dibenzyl ketoxime hydrochloride unexpectedly furnished a pyrazine derivative (67%), presumably via further reaction of the intermediate nitrilium ion in the crystal lattice.

Nitration of styryl ketones with nitrogen peroxide leads to the corresponding α-nitroethylenic ketones in good yield.However, the presence of methoxy groups involves a nitration on the aromatic nucleus.LiAlH4 reduction of α-nitrostyrylketones yields the c
