Abstract

A 1,3,2-oxazaphosphole picks up triplet dioxygen in 1:1 stoichiometry similar to flavin organic co-factors. 1,3,2-Oxazaphosphole catalyzes the oxygenation of triphenylphosphine to triphenylphosphine oxide. The reaction obeys an overall third order rate equation. In a radical pathway, organic hydroperoxide is formed from the catalyst and 3O2, which oxygenates PPh3, similar to flavin cofactors.
