1,3,2-Oxazaphospholes are able to catalyze the oxidation of 3,5-di-
tert
-butylcatechol with
3
O
2
to the corresponding
o
-quinone and
2-aminophenol to 2-aminophenoxazine-3-one in methanol. In both
the cases, an overall third order reaction rate equation and a new
type of biomimetic organocatalyst for oxidation reactions was found.
A one electron transfer of the phenolate, which is formed through
the deprotonation of the substrates by the catalyst, to dioxygen
seems to be rate-determining step.
