Efficient access to five- to seven-membered cyclic ketoimines, through palladium-catalyzed intramolecular imidoylative Heck reaction of alkene-containing isocyanides, has been developed. Consecutive isocyanide and alkene insertion into aryl or alkyl Pd­(II) intermediates takes place in this process. No byproduct derived from monoinsertion or reversed sequence is detected.
