Stoichiometric CO2 reductions using a bis-borane-based frustrated Lewis pair

Abstract

The bis-borane 1,2-C₆H₄(BCl₂)₂ forms an adduct with PtBu₃, but is still capable of exhibiting FLP reactivity with THF and CO₂. The resulting CO₂ species is reduced by Me₂NHBH₃ or [C₅H₆Me₄NH₂]X (X = [HB(C₆F₅)₃], [HB(C₆F₅)₂(C₇H₁₁)]) followed by quenching with water to effect the stoichiometric conversion of CO₂ to methanol.
