Reaction of nitroalkenes or nitrodienes with methyl vinyl ketone (MVK) or acrylate in the presence of the imidazole–LiCl catalyst system provides Rauhut–Currier (vinylogous Morita–Baylis–Hillman) adducts in moderate yield. Under similar conditions (imidazole–hydroquinone), nitroalkenes and nitrodienes undergo self-dimerization to afford the Rauhut–Currier adducts in varying yields. An alternative
