Vibrational Couplings in Hydridocarbonyl Complexes: A 2D-IR Perspective

Hydridocarbonyl complexes, a class of industrially relevant catalysts, contain both the M-H and M-CO moieties. Here, using two-dimensional infrared spectroscopy, we examine the coupling of the typically weak M-H stretching mode and the intense M(CO) mode. By studying a series of Ir(I)- and Ir(III)-based hydridocarbonyl complexes, we show that the arrangement of the H and CO ligands in a trans configuration leads to strong vibrational coupling and mode delocalization. In contrast, a cis arrangement leads to no coupling, with the localized M-H mode having a much larger anharmonicity. These results highlight a promising strategy for enhancing the M-H vibration by intensity borrowing from the strong CO modes in a trans configuration, allowing for direct determination by infrared spectroscopy of both the oxidation (by frequency shifts) and the protonation state (via vibrational coupling) of the complex, in mechanistic studies of proton-coupled electron transfer reactions.

Tetravalent tellurium ligands

Oxidative addition of TeCl4 to Vaska's complex gave the trichlorotelluronium complex [IrCl2-(TeCl3)(CO)(PPh3)2] (structure depicted), which contains a rare example of a structurally characterized tetravalent tellurium ligand. The coordination at the Te(IV) center is - in full agreement with the VSEPR model - distorted trigonal bipyramidal.

Oxidative addition/decarbonylation of αω-alkanedioyl dichlorides. Metallacycle formation via intramolecular reductive cyclization of a pendant acid chloride with samarium(II) iodide

Controlled oxidative addition and decarbonylation at one end of α,ω-alkanedioyl dichlorides is reported with (Ph3P)2Ir(N2)Cl, giving Ir(III) alkyl complexes bearing a pendant acid chloride functionality. The use of the dinitrogen complex enables suppression of competitive intramolecular lactonization processes. Use of 2 equiv of samarium(II) diiodide uniquely promotes intramolecular reductive cyclometalation of one of these complexes, forming a cyclic acyl complex. This cyclization is highly sensitive to both electronic factors in the substrate and the nature and stoichiometry of the reducing agent.
