Vanadium-Induced Nucleophilic IPSO Substitutions in a Coordinated Tetrachlorosemiquinone Ring: Formation of the Chloranilate Anion as a Bridging Ligand

In basic media, the coordinated semiquinone radical in the spin-coupled [(bipy)(CIVO)-O-IV(TCSQ)] 1 (HTCSQ = tetrachlorosemiquinone) undergoes nucleophilic ipso substitution (OH- for Cl-) to generate the chloranilate anion (CA2(-)) that bridges the vanadium(IV) centers, forming a binuclear compound [(bipy)(CIVO)-O-IV(CA)(OVCl)-Cl-IV(bipy)] 2.
