Molybdenum(0)‐Promoted Carbonylative Cyclization of o‐Haloaryl‐ and β‐Haloalkenylimine Derivatives by Oxidative Addition of a Carbon(sp2)Halogen Bond: Preparation of Two Types of γ‐Lactams

Lovely lactams: Synthetically useful γ-lactam derivatives have been prepared through the unique title transformation. By utilizing the characteristic property of the molybdenum complex, two kinds of products (both of which have rarely been obtained by reactions catalyzed by late transition metals) were obtained selectively by adjusting the reaction conditions (see scheme).
