Cooperative bond activations by a tucked-in iron complex

Abstract

Herein, we report the first example of a ‘tucked-in’ iron diphosphine complex, formed through deprotonation of a Cp*–(C₃) (Cp* = C₅Me₅⁻) group by n-butyllithium. The reactivity of this complex was demonstrated by activation of organic and metal-containing substates, including CO₂, benzaldehyde, Br–Au^I–PPh₃, B(C₆F₅)₃, and HBCy₂ (Cy = cyclohexyl).
