The combined use of a copper halide, a silver salt and a phosphane ligand was applied for the catalysis of inter- and intramolecular hydroamination of alkenes. The reactions of unactivated olefins with nitrogen substrates were investigated. Mechanistic investigations demonstrated that the catalytic system generated a Bronsted acid which appeared to be the prominent catalytic species. Copyright

Aromatic amines react with alkenes in the presence of catalytic amounts of aqueous HI to give mixtures ef the corresponding hydroamination and hydroarylation products. While the hydroamination reaction is the preferred pathway for aliphatic alkenes, the h

Nucleophilic addition of sulfonamides and carboxamides to simple alkenes proceeded smoothly using a proton-exchanged montmorillonite catalyst. The spent catalyst was recovered easily from the reaction mixture and was reusable at least five times without any loss of activity. The unique acidity of the proton-exchanged montmorillonite (H-mont) catalyst was found to be applicable to additional reactions: substitution of hydroxyl groups of alcohols with amides and anilines.
