tricarbonylchromium complex, 9 and 10, in 60% yield using ligand exchange with naphthalene and to its hexamethylbenzene−ruthenium complexes 11 and 12 with [RuCl2(HMB)]2 and AgBF4. The cyclopentadienide fused dihydropyrene 5 was synthesized from dimethyldihydropyrene 1 in eight steps, and then on reaction with pentacarbonylmanganesebromide gave the tricarbonylmanganese complex of 5, as two isomers 28
