Reaction
of [NBu4][LCuIIOH] with excess ROOH
(R = cumyl or tBu) yielded [NBu4][LCuIIOOR],
the reversible one-electron oxidation of which generated novel species
with [CuOOR]2+ cores (formally CuIIIOOR), identified
by spectroscopy and theory for the case R = cumyl. This species reacts
with weak O–H bonds in TEMPO-H and 4-dimethylaminophenol
(NMe2PhOH), the latter yielding LCu(OPhNMe2),
which was also prepared independently. With the identification of
[CuOOR]2+ complexes, the first precedent for this core
in enzymes is provided, with implications for copper monooxygenase
mechanisms.
