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.

The NaBH4/C (charcoal) system reduces a variety of carbonyl compounds such as aldehydes, ketones, acyloins and α-diketones to their corresponding alcohols in high to excellent yields. Reduction reactions were carried out in wet THF at r. t. In addition, regioselective 1,2-reduction of α,β - unsaturated aldehydes and ketones was achieved perfectly with this reducing system. By decreasing the amount of aprotic solvent, all reductions took place fast and efficiently under solid-gel condition
