Magnetic susceptibility data reveal significant exchange coupling of Cr<jats:sup>II<\/jats:sup> (<jats:italic>S<\/jats:italic>=2) in <jats:bold>1<\/jats:bold> and large zero\u2010field splitting for Cr<jats:sup>IV<\/jats:sup> (<jats:italic>S<\/jats:italic>=1) in <jats:bold>2<\/jats:bold> owing to strong spin\u2013orbit coupling of the ground state. The Cr<jats:sup>IV<\/jats:sup>\uf8feO compound can also be generated using PhIO, and evidence was gathered that although it is the stable product isolated after excessive O<jats:sub>2<\/jats:sub> treatment, it further activates O<jats:sub>2<\/jats:sub> to yield an intermediate species that oxidizes THF or Me\u2010THF.
