Double nucleophilic aromatic substitution reactions between N-substituted (η⁶-1,2-dichlorobenzene)RuCp⁺ salts and substituted 1,2-benzenediols have been carried out under mild conditions to prepare N-substituted (η₆-dibenzo[b,e][1,4]dioxin)ruthenium(II) complexes. The dibenzodioxin ligands were subsequently liberated by photolysis, with radiation from a sunlamp or from a medium pressure Hg lamp (300 nm).
