Dihydrido Iridium Triisopropylphosphine Complexes as Imine Hydrogenation Catalysts

Dihydrido iridium Triisopropylphosphine Complexes as Imine Hydrogenation Catalysts 

Both monohydrido complexes contain a cyclometalated molecule derived from the N-benzylideneaniline substrate, and the presence of the aniUne Ugand in the later complex seems to be due to some imine hydrolysis caused by adventitious water. Accordingly, this aniline complex practically disappears when carefully dried substrates and solvents are used [29]. 

It is a pleasure to acknowledge the experimental and intellectual contributions made to the various aspects of these studies by the coworkers whose names appear in the references, and without whose contributions this chapter could not have been written. In particular, 1 would like to thank Dr. Eduardo Sola and Prof. Helmut Werner for their stimulahng discussions and collaborations on this subject.
