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

A direct amination of simple cycloalkanes with nitroarenes mediated by peroxides has been discovered. Various secondary arylamines were obtained efficiently from cycloalkanes. The reaction tolerates a wide range of functionalities as well as aqueous condi
HI-catalyzed hydroamination and hydroarylation of alkenes

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

Intermolecular hydroamination or hydroarylation reactions of norbornene and cyclohexadiene performed with catalytic amounts of Br?nsted or Lewis acid in ionic liquids were found to provide higher selectivity and yields than those performed in classical organic solvents. The ionic liquid increases the acidity of the media and stabilizes ionic intermediates through the formation of supramolecular aggregates.
Efficient C-N bond formations catalyzed by a proton-exchanged montmorillonite as a heterogeneous Bronsted acid

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.
Proton-catalyzed hydroamination and hydroarylation reactions of anilines and alkenes: A dramatic effect of counteranions on reaction efficiency

(Matrix Presented) An intermolecular hydroamination reaction of norbornene is presented that uses catalytic amounts of user-friendly TiCl4 and tolerates a variety of functional groups. In addition, a secondary amine is converted using this meth
Rhodium-catalysed hydroamination-hydroxylation of norbornene with aniline, toluidines or diphenylamine
