Herein we report the synthesis of Al-based esters containing halogenated benzene rings. These Lewis adds were paired with phosphines to form frustrated Lewis pairs (FLPs) which could subsequently bind CO2. While these FLPs were not sufficiently water-stable to catalyze the reduction of CO2 to MeOH using NH3BH3 as the reductant, we examine the effect of varying Lewis acid strength. Frustrated Lewis pairs (FLPs) are combinations of Lewis acids and Lewis bases where the add and base are either sterically or geometrically restricted from interacting as strongly as their electronic structures would allow. This effect leads to enhanced reactivity towards small molecules and, consequently, interest in their potential as metal-free catalysts [1-5]. To-date, the biggest success has been based around the ability of a myriad of systems to heterolytically cleave H-2 and perform catalytic hydrogenations [2,3]. Published by Elsevier B.V.
