A Short Synthetic Route to Novel, Highly Soluble 3,8-Dialkyl-4,7-dibromo-1,10-phenanthrolines

A short and convenient synthesis of highly soluble 3,8-dialkyl-4,7-dibromo-1,10-phenanthrolines is described. These compounds are versatile key building blocks for the preparation of macrocyclic oligophenanthrolines with exo-coordination sites.

A Short Synthetic Route to 4,7-Dihalogenated 1,10-Phenanthrolines with Additional Groups in 3,8-Position: Soluble Precursors for Macrocyclic Oligophenanthrolines

A short and efficient preparation of 3,8-dialkylated or 3,8-diarylated 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 can be further reacted by nucleophilic aromatic substitution or Heck-coupling reactions.
