The metallofulvene or carbene complex Ru-II(PI)(PCy3)(2)Cl-2 with PI = 3-phenylindenylidene and Cy = cyclohexyl shows a long-wavelength absorption at lambda(max) = 490 nm which is attributed to a Ru-II -> pi* carbene MLCT transition. MLCT excitation leads to a reversible release of the carbene ligand which can be intercepted by oxygen. The oxygen adduct (or O-oxide) undergoes a fragmentation which yields CO2 and anthracene.
