Intramolecular cyclopropane formation by insertion of an iron–carbene species into a C–H bond
Abstract
The bimetallic carbene complex [Cp*Fe(CO)2(µ-η1,η6-CHCMe2C6H5)FeCp][PF6]22, spectroscopically observed by 1H NMR at –80°C, undergoes intramolecular C–H insertion to give [CpFe(η6-1-phenyl-1-methylcyclopropane)][PF6]3.
