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