“…Iridium-based organometallic complexes have a similar chemistry as rhodium; they possesses unique properties and are ideal catalysts for oxidative addition, hydrogenation, bond breaking, and bond making reactions in various chemical processes. [1][2][3][4][5][6][7][8][9] Several iridium based organometallic complexes (iridium-olefin, arene, allyl, alkyl, and carbene complexes) have been extensively studied for hydrogenation, C-H activation, and oxidative addition. [10,11] Vaska's catalyst [12] and Crabtree's catalyst [13][14][15] are the well-known examples of important iridium-based homogeneous catalysts used for oxidative addition and hydrogenation reactions.…”

Here we report the preparation of first examples of iridium‐based organometallic macromolecules, viz., iridium‐tetra (4‐carboxyphenyl)porphyrin (IrTCPP), iridium‐calix[4]pyrrole (IrCP) iridium‐tetraphenylporphyrin (IrTPP), which are effective catalysts for hydrogenation of levulinic acid (LA) to γ‐valerolactone (GVL) and 1,4‐pentanediol under base free conditions. The turnover number in the range of 1220–2850 is evident for the chosen reaction using iridium macromolecule based catalysts. The heterogenization of homogeneous IrTCPP, IrCP, and IrTPP result in stable reactivity of the catalysts for several runs.

“…30 One very interesting olefin complex, which provides a starting point for a number of their studies, is the ethylene complex (tripod)IrCl(C 2 H 4 ) (14) where tripod = HC(CH 2 PPh 2 ) 3 . 31 This particular ethylene complex has been a rich source of unusual iridium chemistry.…”

The organometallic chemistry of iridium is reviewed. The general classes of complexes of iridium containing iridium to carbon bonds are surveyed. The preparations of iridium olefin complexes, iridium arene complexes, iridium carbonyl complexes, iridium cyclopentadienyl complexes, and other types of complexes are covered along with the use of those classes of compounds in preparing other organometallic iridium species. In addition, three areas in which organoiridium compounds find particular application are specifically reviewed: catalysis utilizing organometallic compounds of iridium, carbon–hydrogen (CH) bond activation chemistry with iridium, and hydrodesulfurization (HDS) studies using iridium. References to other reviews, to monographs, and to the primary literature are provided in all cases.
