Captodative formyl(amino)alkenes react with N,O-binucleophiles in a cascade fashion to result mainly in dioximes (in the case of hydroxylamine) or oxazoline derivatives (in the case of 2-amino-2-methylpropanole).

ipso-Substitution of the halogen atom in 2-halo-2-alkenals under the action of secondary amines proceeds via three consecutive steps: addition, nucleophilic substitution, and beta-elimination (the Ad(N)-S-N-E mechanism). The main intermediates arising in the reactions of 2-chloropropenal and 2-chloro-2-butenal with piperidine were detected by NMR spectroscopy. A general scheme of the reaction is proposed.
