The activation of small molecules by transition metal complexes via ligand substitution or oxidative-addition has historically received a great deal of attention since these reactions are requisite for catalytic processes. Hydrodesulfurization (HDS) is an important process for the removal of sulfur from fossil fuels. Our work focused on the synthesis and reactivity of iridium complexes stabilized by the aryldiphosphine, (C6H5)2PCH2P(C6H5)2, and the alkyl diphosphine, (C6H11)2PCH2P(C6H11)2. These complexes were reacted with sulfur-containing compounds to determine their efficacy in the activation of sulfur-hydrogen bonds. The solution structures of resulting complexes complexes will be described.
