Methyltrioxorhenium CH3ReO3 (MTO, 1) is one of the most active catalys
ts of the Baeyer-Villiger oxidation of cyclic ketones by use of H2O2 a
s oxidant. In contrast to the chemistry of established molybdenum and
tungsten peroxo complexes, the bis(peroxo) complex [CH3ReO(O-2)(2).H2O
] reacts stoichiometrically with ketones. The electronic character of
the active species was determined by spectroscopy and by application o
f an oxygen transfer probe.
