Hydrogen bonding-assisted tautomerization of pyridine moieties in the coordination sphere of an Ir(I) complex.
Ir(I)-induced tautomerization of a pyridine moiety to a carbene in 2,3-bipyridyls has been successfully achieved where an amide group plays a key role as a hydrogen-bonding acceptor and the carbene tautomer is stabilized by both chelation effect and by hydrogen-bonding.
