Catecholate catwalk : Monomeric manganese(III) catecholato and manganese(II) semiquinonato complexes as the substrate‐binding model of catechol dioxygenase have been synthesized and structurally characterized. The semiquinonato complex reacted with molecular oxygen to give ring‐cleaved products and benzoquinone in the catalytic condition.
