Pentalene and Acepentalene Complexes

The organometallic chemistry of pentalene has been reviewed here, only representative examples of this chemistry are presented [95,153-156]. 

In addition to the complexes mentioned, there are some in which the pentalene ligand is separated into a cyclopentadienyl and an allyl part, comparable to ring slippage chemistry and the so-called indenyl effect [162,168].
