Palladium(II)-Catalyzed Intramolecular Aminobromination and Aminochlorinaof Olefins. — Optimal conditions for the title reaction are developed. The use of
11- 058 tion
a stoichiometric amount of Cu(II) halide to aid in halogen transfer and catalyst oxidation leads to high yields of cyclized products. The degree of regioselectivity varies with
the substrate structure. It is found that the solvent, reaction temperature, and the nature
of the copper halide influence the course of the reaction. — (MANZONI, M. R.;
