Properties and reactivity of silicon-and boron-containing reduced2,2'-bipyridyl compounds

摘要

2,2'-Bipyridyl is one of the simplest and most common redox-active ligands.Thesingly and doubly reduced forms are both accessible,typically stabilized in complexes withGroup 1 metals,magnesium,or transition metals.1 In most examples,2,2'-bipyridyl actsas an electron reservoir,transferring electrons to or from the metal.In addition to its directapplication as a redox-active ligand,2,2'-bipyridyl can be incorporated into complexmolecules such as supramolecular structures and conjugated polymers to take advantage ofits diverse redox chemistry,π electronic structure,and geometry.2
