title: Vanadium-induced nucleophilic IPSO substitutions in a coordinated tetrachlorosemiquinone ring: formation of the chloranilate anion as a bridging ligand.
abstract: In basic media, the coordinated semiquinone radical in the spin-coupled [(bipy)ClV(IV)O(TCSQ)] 1 (HTCSQ = tetrachlorosemiquinone) undergoes nucleophilic ipso substitution (OH- for Cl-) to generate the chloranilate anion (CA(2-)) that bridges the vanadium(IV) centers, forming a binuclear compound [(bipy)ClV(IV)O(CA)OV(IV)Cl(bipy)] 2.
