Naphthalene-Mediated Electronic Communication in Tetrakis-(imino)pyracene Complexes

摘要

Previous work with monofunctional bis(imino)acenaphthene (bian) ligands demonstrated that they are capable of accepting zero, one, or two electrons from lanthanide bis(cyclopen-tadienides) depending on the choice of the metal and the steric/electronic characteristics of the bian ligand substitu-ents. More recently, the first example of a bifunctional analogue of the bian ligand class has been reported, namely the tetrakis(imino)pyracene (tip) ligand la (Scheme 1).
