In order to examine the formation of N-vinyl nitrones the activated alkyne (II) and allene (VI) are reacted with oximes, e.g. (I). Three groups of products are obtained: the isomeric oximes (III), the stable O-addition products (IV) and the isoxazoline (V). With allene (VI) the reaction proceeds via
