Lead tetra-acetate reacts with benzaldehyde toluene-$-and benzenesulphonylhydrazone to give the corresponding monoacetoxylated compounds (I) and (111). The reaction effects substitution at the benzylic carbon atom rather than at the nitrogen atom directly linked to the sulphonyl group. Lithium aluminium hydride reduction of the benzaldehyde and salicylaldehyde toluene-p-sulphonylhydrazone gives di-p-tolyl disulphoxide.
