Single and double C–C bond formation via iron–carbene species: access to new π- and σ,π-vinylarene complexes
Abstract
The bimetallic complex [(η5-C5Me5)Fe(CO)2{µ-η1,η6-CH(OMe)CH2C6Me5}Fe(η5-C5H5)][PF6](3), which is readily prepared by electrophilic carbene–alkene coupling between (1) and (2), is specifically converted into either the η6-vinylpentamethylbenzene complex (4) or the related dinuclear (µ-η1, η6-vinylarene) complex (E)-(5).
