Oxygen atom transfer (OAT) reactions between closed shell org. mols. under thermodynamically favorable conditions are well known, but these reactions would not occur under normal reaction conditions. Transition metal complexes have been utilized extensively in catalyzing OAT to and from org. compds. For instance, oxorhenium complexes have been successfully investigated working as catalysts for the transfer an oxygen atom from pyridine N-oxide to an appropriate oxygen acceptor such triphenylphosphine. In this study, several oxorhenium(V) complexes ReO(RNCH2CH2)2NMeX (R= Mes, C6F5; X= Me, Cl, I) have been prepd. and their reactivity in OAT reactions was studied. Varying the ligand X from a strong donar to a poor donor, or changing the R substituent on the diamido amine ancillary ligand will affect the reactivity of OAT reactions dramatically.
