Hydrolysis of o-nitrobenzyl tosylate in CH3CN:H2O (1:1, v/v) gave o-nitrobenzyl alcohol and o-nitrosobenzaldehyde in 1.8:1 ratio. Formation of o-nitrosobenzaldehyde indicates that the nitro group participates in the leaving of the tosylate group. o-Nitrosobenzaldehyde was reduced by biological thiols to give o-aminobenzaldehyde. Reaction of o-nitrosobenzaldehyde with 1 mol of benzylamine afforded
