Miscellaneous Catalytic Applications with Industrial Potential 

Besides the reaction discussed above, several Ir-catalyzed reactions are available which probably have some potential to be applied in industrial syntheses. 

Asymmetric allylic substitutions are widely applied in organic synthesis, using various metal complexes, chiral ligands, nucleophiles and allyl systems [39]. Although Pd is often the metal of choice, this is not the case for monosubstituted allylic substrates, where most Pd catalysts predominantly produce the achiral linear product. In contrast. Mo, W and Ir catalysts preferentially give rise to the desired branched products and, in recent years, a number of very effective Ir catalysts for various substrates have been developed [40]. Since, to the best of our 

Ir-diphosphine complexes have been shown to catalyze a number of potentially interesting C—C coupling reactions [41]. Special mention should be made of the various transformations of alkynes (cycloaddition, isomerization, dimerization, alkynylation), selected aldol and carbonylation reactions, even though the synthetic potential of some of these reactions has not been explored. 

Besides preparative applications, Ir complexes such as lr(cod)(acac) or [cp lr(PMe3)H3]OTf have successfully been applied for hydrogen/deuterium (H/
