Reaction of tricarbonylcycloheptatrieneiron with base: the tricarbonylcycloheptatrienyliron anion
Abstract
Tricarbonylcycloheptatrieneiron (1) exchanges stereoselectively with MeO– in MeOD immeasurably faster than the uncomplexed hydrocarbon; reaction of (1) with butyl-lithium in tetrahydrofuran gives the first reported complex of the cycloheptatrienyl anion.
