Abstract

The direct addition of NH across a CC multiple bond (hydroamination) was efficiently catalysed in a liquid-liquid two-phase system. The latter comprised a polar catalyst phase of Zn(CF3SO3)2 in the ionic liquid 1-ethyl-3-methylimidazolium trifuoromethanesulfonate and a substrate mixture in heptane. The possibility of catalysing different hydroamination reactions continuously was demonstrated.

Aminotroponiminate zinc complexes as catalysts for the intramolecular hydroamination

“…However, zinc based catalysts have been almost unexplored in hydroamination. Before we began our studies in this field, the only molecular zinc compound investigated for catalytic hydroamination was zinc triflate [113,114]. This research was performed in 2000 by Müller et al and high activities compared to other group 7e12 transition-metal complexes were observed for zinc triflate.…”

Titania Nanoparticles Stabilized HPA in SBA‐15 for the Intermolecular Hydroamination of Activated Olefins

“…[17] Significant effort has, therefore, been made to develop metal catalyzed HA processes. [20,21] Various ion exchanged zeolites and clays [22][23][24][25] and immobilized zinc salts [26] have been successfully used for the cyclization of 6-aminohex-1-yne and intermolecular HA of phenylacetylene with aniline. Immobilized transition metal complexes were also used in the addition of 4-isopropylaniline to phenylacetylene.…”
