Rc. Cambie et al., TOWARDS THE SYNTHESIS OF AMINODIBENZO[B,E][1,4]DIOXIN DERIVATIVES VIACATIONIC RUTHENIUM COMPLEXES, Journal of organometallic chemistry, 507(1-2), 1996, pp. 1-21
Double nucleophilic aromatic substitution reactions between N-substitu
ted (eta(6)-1,2-dichlorobenzene)RuCp(+) salts and substituted 1,2-benz
enediols have been carried out under mild conditions to prepare N-subs
tituted (eta(6)-dibenzo[b,e][1,4]dioxin)ruthenium(II) complexes. The d
ibenzodioxin ligands were subsequently liberated by photolysis, with r
adiation from a sunlamp or from a medium pressure Hg lamp (300 nm).
