Abstract
The dicationic arene complexes [(p-cymene)Ru(PhCH2CH2[CH2]nOH)][OTf]2 and [Cp*Ir(PhCH2CH2[CH2]nOH)][OTf]2 (n = 1−2) react with K2CO3 to cleanly generate spirocyclic cyclohexadienyl complexes through intramolecular nucleophilic addition of the alkoxide at the ipso carbon of the arene ligand. When the internal nucleophile is the bulkier benzenesulfonamide group, cyclohexadienyl complexes derived from both ipso and ortho intramolecular nucleophilic addition are formed.
