Abstract
A short and efficient preparation of 3,8-dialkylated or 3,8-dialkylate d 1,10-phenanthrolines-4,7-diones is described. Their chlorination or bromination furnishes the corresponding, highly soluble 4,7-dichloro- or 4,7-dibromo phenanthrolines that constitute versatile precursors to macrocyclic oligophenanthrolines with exo-coordination sites. They ca n be further reacted by nucleophilic aromatic substitution or Heck-cou pling reactions.
