Abstract
The synthesis and characterization of a bifunctional bridging ligand for use in the study of photoinduced electron and energy transfer was undertaken. The synthesis was approached in two parts. First, 4-trimethyltin-2,2’-bipyridine was prepared in five steps from 2,2’-bipyridine. Next, a 5-bromo-m-(CHCHCO2H)2-xylene compound was synthesized from 5-bromo-m-xylene. These components represent the two halves of the desired ligand, where the bipyridine fragment is available binding a RuII metal center and the carboxylic acid functional groups can support formation of a dinuclear FeIII core. The final ligand was synthesized via a Stille cross coupling reaction to form 4-(3,5-di(methyl-3-propionate-1-ene))benzyl-2,2’-bipyridine.
