Redox active aluminium(iii) complexes convert CO2 into MgCO3 or CaCO3 in a synthetic cycle using Mg or Ca metal

Abstract

Redox-active Group 13 molecules possess the unusual combination of concomitant redox and acid–base reactivity. These combined properties enable regeneration of a metal hydroxide complex in a cycle for conversion of CO2 into carbonate salts. Reaction of (IP)2Al(OH) (M = Al, Ga) with 1 atm of CO2 affords [(IP)2Al]22κ12-OCO2). Subsequent reduction affords MgCO3 or CaCO3 and two equivalents of [(IP2−)2Al], which can be reoxidized to (IP)2Al(OH) to close a cycle.
