Description

General description

BMIMPF₆ is used as an efficient reaction medium for various synthetic and catalytic transformations.

1-Butyl-3-methylimidazolium hexafluorophosphate is an imidazolium-based, hydrophobic, room temperature ionic liquid (RTIL). It can be prepared by reacting 1-methylimidazole with chlorobutane. Gaseous hydrofluorocarbons (HFCs) such as fluoromethane, fluoroethane and 1,1,2,2-tetrafluoroethane are soluble in BMIMPF₆.

Application

1-Butyl-3-methylimidazolium hexafluorophosphate is an ionic liquid employed in many environmentally friendly reactions.

It can also be used as a medium for reactions such as:

• Ring-closing metathesis of diene and enyne substrates in the presence of a novel recyclable ruthenium carbene complex.
• Nickel(II)acetylacetonate catalyzed oxidation of aromatic aldehydes to the corresponding acids using dioxygen as the oxidant.
• Lipase-catalyzed enantioselective acylation of allylic alcohols.
• Allylation of aldehydes using tetraallylstannane to yield homoallylic alcohols.
