Abstract

Phosphonium-based ionic liquids form new ionic liquids when treated with borane (BH₃), and these ionic liquids are useful for reduction reactions involving carbonyl compounds. Alane (AlH₃) reacts with the phosphonium cation, nevertheless the resulting solutions are capable of reducing esters to aldehydes. Phosphonium-based ionic liquids may serve as useful materials for reactive gas transport, and hence may serve as a fluid alternative to porous materials and may provide a convenient method of safely transporting boron hydrides for a variety of applications.
