Description

General description

1-Butyl-2,3-dimethylimidazolium tetrafluoroborate is a task-specific ionic liquid.

Application

[bdmim]BF₄ can be used as a solvent when lipase needs to be recycled during lipase-catalyzed transesterification with vinyl acetate as acyl donor. The [bdmim]BF₄/toluene biphasic solvent forms an efficient system for the Negishi cross-coupling reaction between aryl zinc halides and aryl iodides.

Other Notes

Ionic liquid, suitable for use in strongly basic conditions, for aldol condensations
