An aluminum carbenoid is the efficient cyclopropanation reagent for the transformation of 2-alkenyl amines into cyclopropyl amines. The addition of iodine facilitates the cyclopropanation of poorly reactive 2-alkenyl amines.

The palladium-catalyzed reaction between aryl or perfluoro-alkyl iodides and tertiary allylicamines provides a practical route to 3-aryl- or 3-perfluoroalkyl-allylic amines. The outcome of the arylation of tertiary allylicamines can be affected by a change of solvent.

Site-selective amination towards tertiary aliphatic allylamines
amination of olefins with secondary alkyl amines to afford allylic amines, eliminating the need for oxidants. This method is compatible with a broad scope of olefins and can be extended to achieve a site- and diastereoselective amination of terpenes. Mechanistic studies disclose that the reaction proceeds via a cobaloxime-promoted hydrogen atom transfer pathway to afford the product that results from cleavage
