Gs. Zhang et al., The cleavage of p-nitrophenylhydrazones and semicarbazones with ammonium chlorochromate adsorbed on alumina under non-aqueous conditions, SYN COMMUN, 29(7), 1999, pp. 1165-1170
Deprotection of p-nitrophenylhydrazones and semicarbazones to their parent
aldehydes and ketones in good yields has been carried out by using ammonium
chlorochromate adsorbed on alumina under mild conditions.
