A novel iridium-catalyzed ring-opening reaction of azabicyclic alkenes with a variety
of fluoroalkylamines was developed. The reaction gave a series of fluorinated trans-1,2-diamine derivatives in good to excellent yields (up to 98%) under relatively
mild conditions. The effects of various ligands, catalyst loading, solvents, and temperatures
on the yield of the reaction were also investigated. This is the first time that fluorinated
compounds were synthesized by incorporating a series of fluoroalkylamines into hydronaphthalene
skeleton.
