Amberlyst|r A-21, ion exchange resin is used as a heterogeneous catalyst for conversion of carbonyl compounds to oximes by reacting with hydroxylamine hydrochloride. It is an effective catalyst for the Michael addition of nitroalkanes to methyl acrylate.
Macroreticular weakly basic anion-exchange resin, free base, suitable for non-aqueous applications.
Effective catalyst for the Michael addition of nitroalkanes to methyl acrylate: Synthesis, 711 (1987), and also for the cleavage of 2-nitrocycloalkanones: Synthesis, 355 (1992). Promotes the Henry (nitro-aldol) reaction of aldehydes with nitroalkanes giving superior results to conventional conditions: Liebigs Ann. Chem., 1235 (1994); J.
