Cooperative bond activations by a tucked-in iron complex.

Herein, we report the first example of a 'tucked-in' iron diphosphine complex, formed through deprotonation of a Cp*-(CH̲ 3 ) (Cp* = C 5 Me 5 - ) group by n -butyllithium. The reactivity of this complex was demonstrated by activation of organic and metal-containing substates, including CO 2 , benzaldehyde, Br-Au I -PPh 3 , B(C 6 F 5 ) 3 , and HBCy 2 (Cy = cyclohexyl).
