Frontispiz: CO2 Reduction at a Borane-Modified Iron Complex: A Secondary Coordination Sphere Strategy

Bifunctional complex design can enable selective activation of the strong C=O bonds in CO2. Much like a fiddler crab, the {Fe-H/Cp*-BCy2} complex employed by Marcus W. Drover and co-workers in their Research Article (e202421599), features two distinct "claws". This study highlights that cooperativity between the iron hydride and pendant Lewis acidic borane is integral to facilitate the reduction of CO2 to a C1 product.
