A convenient synthesis of nitrones by N-alkylation of O-trimethylsilyloximes

Aldoxime and ketoxime-O-trimethylsilyl ethers can be alkylated with trialkyloxonium tetrafluoroborates and alkyl triflates at or below room temperature to produce nitrones in good yields.

Synthesis of nitrones of the polyfluoroaromatic series

1. Anils of polyfluorobenzophenones are oxidized by trifluoroperacetic acid in methylene chloride at 20°C forming polyfluoro-substitutedα,α,N-triarylnitrones. A condition of this direction for the reaction is the presence on the carbon atom of the azomethiae bond of a least one pentafluorophenyl group. 2. Oxidation of the anil of pentafluorobenzaldehyde with trifluoroperacetic acid led to the formation of pentafluorobenzoic acid anilide and pentafluorobenzaldehyde.

Nuclear polarization in the martynoff rearrangement of nitrones

A novel synthesis of nitrone (I) is described; 1H n.m.r. CIDNP emission in the formation of oxime ether (II) from thermolysis of (I) implicates caged radical pairs in the migration process.

A new synthesis of nitrones from aromatic nitro-compounds and carbanions by nucleophilic replacement of hydrogen

Diphenylacetonitile and some nitrobenzenes in the presence of saturated KOH or MeONa in methanol react to yield substituted triaryl nitrones.
