The reaction of imides and activated amides with phosphoranes provides a simple route to enamides, bis [alkenyl] amincs, and enamines. Experiments to determine the scope and limitations of these reactions are summarised in this review. Some of the results are taken from investigations with other aims. As well as the dependence on structure, configurational and tautomeric aspects of the reaction are described. The Wittig alkenylation of the imides ...
