    Abstract

    The O2 affinity of Co(II)Salen complexes 1−4 and their reactivity in cyclohexene oxygenation reactions of Co(II)Salen complexes 1−4 are modulated by noncovalent interactions such as hydrogen bonding and steric hindrance using a functionalized diamino bridge. Higher O2 affinity is observed in the case of efficient hydrogen-bonding interactions (complex 1), while increased steric hindrance (cis vs trans diamino bridge) around the Co-coordinated O2 is influencing the reactivity of the complexes.
