Octafluorocyclooctatetraene (OFCOT) reacts with some metal carbonyl anions [ML n ] − to give monosubstitution products (C 8F 7)ML n [ML n = Mn(CO) 5, Re(CO) 5, Fe(CO) 2(η-C 5H 5)]. 19F and 13C { 19F} NMR studies show that the cyclooctatetraene ring in these monosubstitution products does not undergo rapid ring-inversion or bond shifting on the NMR time scale. Reaction of OFCOT with [Co(CO) 4] − affords the distributed derivative [(C 8F 6)Co 2(CO) 6] as the only product in poor yield.
