Abstract

PF6-, together with suitably substituted cations often results in an altered chemical reactivity and selectivity. Among the commonly used ionic liquids, 1-butyl-3-methylimidiazolium hexafluorophosphate [(bmim) PF6] is a common reaction medium for the various organic transformations such as hydrogenation,12 hydroformylation,13 oxidation,14 etc. We now report the alkynylation of ketones promoted by potassium hydroxide in ionic liquid [(bmim) PF6] as a solvent furnishing ...
