The present invention is directed to a process for addition of amines to carbon-carbon double bonds in a substrate, comprising: reacting an amine with a compound containing at least one carbon-carbon double bond in the presence a transition metal catalyst under reaction conditions effective to form a product having a covalent bond between the amine and a carbon atom of the former carbon-carbon double bond. The transition metal catalyst comprises a Group 8 metal and a ligand containing one or more 2-electron donor atoms. The present invention is also directed to enantioselective reactions of amine compounds with compounds containing carbon-carbon double bonds, and a calorimetric assay to evaluate potential catalysts in these reactions.

The intermolecular hydroamination of 1,3-cyclohexadiene with aniline using zeolite catalysts was investigated. The reaction mechanism and the influence of amine basicity on the rate of reaction were Studied. Zeolite H-BEA was the most active catalyst, whereas the incorporation of Zn2+ (Zn/H-BEA) led to decreasing catalytic activity, indicating that the reaction is catalyzed by Bronsted acid sites. Subtle shape selective effects determine the reactivity and selectivity of the zeolites. (c) 2006 Elsevier Inc. All rights reserved.
