"HALF-OPEN COBALTOCENE" CHEMISTRY: DIENE REPLACEMENT VS. HYDRIDE ABSTRACTION BY THE TRIPHENYLMETHYL CATION

Article abstract of DOI:10.1016/0022-328X(86)82089-7

Cyclopentadienyl(η⁴-2,4-bis(trifluoromethyl)-1,3-pentadiene)cobalt has been prepared by the reaction of the fluorinated diene with (cyclopentadienyl)bis(ethylene)cobalt.An attempt to bring about hydride abstraction from the former compound using the triphenylmethyl cation has instead led to a replacement of the fluorinated diene by an η⁵-(C6H5)3C(1+) ligand.
