Hot and bothered? Frustrated Lewis pairs comprising phosphine and borane react to reversibly bind and release CO 2 , offering a rare example of metal‐free CO 2 sequestration. The mechanism of formation of these CO 2 derivatives 1 and 2 (see scheme) by almost simultaneous PC and OB bond formation was characterized by quantum chemical calculations.
