CIDNP Studies of the Oxidation of N-(p-Tolylsulfonyl)-N′-triphenylmethylhydrazine

The 13C-CIDNP spectra were observed during the oxidation of N-(p-tolylsulfonyl)-N′-triphenylmethylhydrazine. The formation of sulfone and sulfinic ester as recombination products in a solvent cage was established from the signs of polarization.
