Partial photocatalytic oxidation of cyclopentene over titanium(IV) oxide

In analogy with cyclohexane, a group of oxidation products appeared mainly including cyclopent-2-en-1-one (in much lower quantities also cyclopent-2-en-1-ol). The epoxide fraction involved mostly 6-oxabicyclo[3.1.0]hexane, appearance of other products of this type was marginal.
