Cyclic Imidoyl Halides

Abstract

In the cyclic series imidoyl halides are reported only for five-, six-, and seven-membered ring systems. However, it was demonstrated recently that 2,2-dichloroaziridines, which are obtained by addition of dichlorocarbene to C=N double bond compounds, react as iminium chlorides. The synthetic methods for the cyclic imidoyl halides are similar to those used for the preparation of the linear species. Therefore, emphasis is focused on the reactions of cyclic imidoyl halides rather than on their synthesis. The organization of this chapter also differs from that of the previous chapters because it is based on ring size rather than on the difference attributable to substituents attached to the C=N double bond system.
