Application

[Ir(dtbbpy)(ppy)2]PF6 is an iridium-based photocatalyst which is used to drive various photochemical reactions such as:
  • Coupling of N-arylamines and nitroalkanes via an oxidative aza-Henry reaction.
  • Atom transfer radical addition (ATRA) of haloalkanes to alkenes and alkynes.
  • Conversion of 2-bromoanilides to the corresponding 3,3-disubstituted oxindoles.
  • Aryl-alkyl C−C reductive cross-coupling reactions.
