Palladium-catalyzed Aromatic Amination of Aryl Halides by Means of Aminotin Compounds

Abstract

The reaction of (diethylamino)tributyltin with aryl bromides in the presence of a catalytic: amount of PdCl2[P(o-tolyl)3]2 gave N, N-diethylaniline derivatives. The reaction was a new kind of amination different from ones through aryne or SRN 1 mechanism. The scope and limitation of the reaction were surveyed. Application to the reaction of a variety of aminotin compounds has some limitations, and the relationship between the structure of aminotin compounds and the yield of the product was not cleared. © 1985, The Chemical Society of Japan.
