Abstract
<jats:title>Abstract</jats:title><jats:p>The reactivity of complexes of triphos [CH<jats:sub>3</jats:sub>C(CH<jats:sub>2</jats:sub>PPh<jats:sub>2</jats:sub>)<jats:sub>3</jats:sub>] and CoCl<jats:sub>2</jats:sub> towards dioxygen has been investigated. Reaction of the pseudo‐tetrahedral complex (η<jats:sup>2</jats:sup>‐triphos)CoCl<jats:sub>2</jats:sub> (<jats:bold>1</jats:bold>) with dioxygen yields after work‐up the mixed phosphane/phosphane oxide ligands triphosO and triphosO<jats:sub>2</jats:sub>. The novel ligand triphosO<jats:sub>2</jats:sub> can be obtained in quantitative yield using catalytic amounts of <jats:bold>1</jats:bold>. In order to gain some insight into the catalytic dioxygen activation reaction, experiments with various triphos/Co/Cl species, in different solvents and at several concentrations have been carried out. A mechanism involving two separate reaction pathways is proposed. Complexes of triphosO and triphosO<jats:sub>2</jats:sub> with CoCl<jats:sub>2</jats:sub>, [η<jats:sup>2</jats:sup>‐(<jats:italic>P, P</jats:italic>)‐triphosO]CoCl<jats:sub>2</jats:sub> (<jats:bold>4</jats:bold>), and [η<jats:sup>2</jats:sup>‐(<jats:italic>P, O</jats:italic>)‐triphosO<jats:sub>2</jats:sub>]CoCl<jats:sub>2</jats:sub> (<jats:bold>5</jats:bold>), which are present as intermediates in the oxygenation reaction, have been isolated and fully characterized including X‐ray structural analyses.</jats:p>
