CO 2 fixation and reduction to value-added products is of utmost importance in the battle against rising CO 2 levels in the Earthsa tmosphere.A no rganoaluminum complex containing aformal aluminum double bond (dialumene), and thus an alkene equivalent, was used for the fixation and reduction of CO 2 .The CO 2 fixation complex undergoes further reactivity in either the absence or presence of additional CO 2 ,r esulting in the first dialuminum carbonyl and carbonate complexes, respectively.D ialumene (1)c an also be used in the catalytic reduction of CO 2 ,p roviding selective formation of af ormic acid equivalent via the dialuminum carbonate complex rather than aconventional aluminum-hydride-basedc ycle.N ot only are the CO 2 reduction products of interest for C 1 added value products,b ut the organoaluminum complexes isolated represent as ignificant step forwardi nt he isolation of reactive intermediates proposed in many industrially relevant catalytic processes.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
