The heterogeneous reactions of [(Ph3P)2IrH2]3PW12O 40 with CO, PF3, C2H4, C2H2, CH3CH=CH2, c-C5H8, C6H6, CH3C6H5, 2,3-dimethyl-1,3-butadiene, isoprene, butadiene, Me3SiH, C2F4, CF3CF=CF2, CF2=CFCl, CH3C(O)H, ethylene oxide, CH3OH, and H2O are described. The chemistry can be described in terms of either addition of iridium to a substrate C-H bond to form intermediates that may optionally eliminate H2 or addition of Ir-H to a C=C bond. It is proposed that these reactants gain access to essentially all of the iridium sites by dissolving in the hydrophobic regions of the lattice of the low surface area iridium oxometalate.

Hydrogenation of [(Ph3P)2Ir(C8H12)] 3PW12O40 in a solid-gas reaction produces [(Ph3P)2IrH2]3PW12O 40. EXAFS studies of the molybdenum analogue indicate the presence of isolated, lattice-stabilized (Ph3P)2IrH2+ ions. H-D exchange with CD3CH=CH2 occurs via a reversible C-H addition reaction that also produces [(Ph3P)2IrH(π-C3H5)] 3PW12O40 and scrambles the C3D3H3 deuterium label. Exchange with toluene is selective and involves activation of aromatic but not aliphatic C-H bonds. Slow exchange with c-C6D12 also occurs.
