Naphthalene and related conjugated polycyclic arenes readily coordinate through one carbocyclic ring to Mn(CO)3+. The resulting complexes, e.g., (η6-naphthalene)Mn(CO)3+, function as very effective manganese tricarbonyl transfer (MTT) reagents, largely because of facile η6→η4 ring slippage. The MTT complexes can be used to synthesize a range of novel organometallic systems, including metal-carbonyl-capped metallocenes, and homo- and heteronuclear bimetallic naphthalene complexes. They are also the basis for the complexation and activation of benzothiophenes to desulfurization and of hydroquinones to deprotonation and self-assembly into supramolecular quinonoid coordination networks.
